Trivia: Big, burly Dan Blocker only did a handful of movies in his 17-year acting career, but he became one of the most beloved and popular television stars of the 1960s for his portrayal of Hoss Cartwright on the Western series Bonanza. Weighing 14 pounds at birth, Blocker was the largest baby ever born in Bowie County, TX. At 18, he stood 6'3" and weighed close to 300 pounds, and was legendary for his physical prowess. Blocker attended the Texas Military Institute and studied for his B.A. at Sul Ross State College, where he initially majored in athletics. His build accidentally led him to the drama department for a production of Arsenic and Old Lace -- a stage hand was needed who was big and strong enough to quickly remove the dummies representing corpses on the set, between acts. While working on the production, Blocker was bitten by the acting bug and switched his major to drama. He pursued his theatrical aspirations in earnest after graduation, working in one season of summer stock before he was drafted. Blocker served in combat during the Korean War, after which he earned a master's degree, married, moved to Los Angeles, and settled down to raise a family, earning his living as a high school teacher. It was his successful audition for the small role of a cavalry lieutenant on Gunsmoke during the 1956 season, in the episode "Alarm at Pleasant Valley," that rekindled Blocker's interest in an acting career. Over the next three years, he took any work that he could get, on programs like Sgt. Preston of the Yukon, Cheyenne, Tales of Wells Fargo, Zane Grey Theater, Wagon Train, Colt .45, Zorro, Maverick, and Richard Diamond, Private Detective. Blocker also got some movie work, portraying a bartender in the offbeat murder mystery The Girl in Black Stockings and an android in Outer Space Jitters, a very late Three Stooges short. His career took an upturn when he got a guest-starring role in an episode of the series The Restless Gun, starring John Payne, in 1958; his work was good enough to catch the attention of the producer, David Dortort. A year later, Dortort was putting together a new, hour-long Western series called Bonanza and cast Blocker in the role of "Hoss" Cartwright, the big-boned, good-natured middle son in a ranching family near Virginia City, NV, set in the mid- to late 19th century (the time frame of Bonanza was always vague, with stories shifting between the early 1860s to the 1870s and 1880s). Blocker's character's real name, incidentally, was Eric, but Hoss -- a nickname from his mother's Norwegian language that meant "friend" -- was what he was known as to everyone on the series and all viewers. Despite the weaknesses in the scripts during the early seasons, the role was a dream part for the actor, who got a chance to display his gentle, sensitive side as well as his gift for comedy, and also work in a serious dramatic context as well on many occasions, and show off his brute strength as well. It is arguable that Blocker was the most popular member of the cast during the 1960s; he was especially beloved of younger viewers, in part because his character was always very sympathetic to children. In contrast to the other stars of the series, Blocker's big-screen career wasn't halted by his work on Bonanza. He appeared in The Errand Boy, playing himself in an uncredited cameo, and played a role in the Frank Sinatra movie Come Blow Your Horn. Blocker got his first major movie part five years later in the Sinatra film Lady in Cement (1968), playing Waldo Gronsky, a burly, potentially murderous thug who hires private detective Tony Rome (played by Sinatra) to find his missing girlfriend. By the end of the 1960s, Blocker was taken seriously enough as an actor to star in two features, Something for a Lonely Man, a beautiful and poignant Western/comedy-drama, and the broader comedy The Cockeyed Cowboys of Calico County. Some of Blocker's television appearances separate from Bonanza also reflected his personal side -- his politics were essentially liberal Democratic (in sharp contrast to the conservative Republican sympathies of his co-stars Michael Landon and Lorne Greene), and he appeared in several public service announcements promoting brotherhood and racial tolerance, as well as on one television special that gently satirized American popular culture, starring Henry Fonda. He was also part of the liberal contingent in the 1971 John Wayne-hosted patriotic special Swing Out, Sweet Land. In 1972, Blocker was chosen for what could have been the breakthrough role to a major movie career, when he won the part of Roger Wade, the has-been author in Robert Altman's revisionist detective movie The Long Goodbye. In May of that year, however, he went into the hospital for routine gall bladder surgery, and during recovery he died suddenly of a blood clot in his lung. Sterling Hayden replaced Blocker in The Long Goodbye, which was dedicated to the actor's memory. Blocker's passing, immediately before the shooting for the 1972-1973 season of Bonanza was to begin, signed the death knell for the series. The cast and crew were genuinely shaken by his sudden death; scripts had to be hastily rewritten to explain the passing of Hoss Cartwright, and Blocker's absence and the reason behind it removed any element of lightheartedness that the series had displayed. The final season, despite the best efforts of surviving stars Lorne Greene, Michael Landon, and David Canary, was characterized by grim, downbeat stories and a dark mood that seemed to repel longtime viewers. Coupled with this change in tone, the NBC network moved Bonanza from its longtime Sunday nighttime slot to Tuesday nights, where it died a quick death, cancellation coming halfway through the 1972-1973 season. Blocker left behind a wife and four children, among them actor Dirk Blocker and director/producer David Blocker. He also left behind a legacy of good will that survives to this day, as Bonanza is in perpetual reruns on various cable channels, decades after its cancellation. Significantly, the final season, in which he did not appear, is the body of episodes that is shown (and requested) the least of its 14 years' worth of programs.

Trivia: Pernell Roberts worked such odd jobs as butcher, forest ranger and tombstone-maker while studying acting and singing and scouting around for off-Broadway jobs. Roberts' film debut, in a characteristic Deep Brooder role, was in 1958's Desire Under the Elms. From 1959 through 1966, Roberts co-starred as black-clad, taciturn Adam Cartwright on Bonanza. "Aloof, rebellious and outspoken" was how Bonanza producer David Dotort summed up Roberts, who fought tooth and nail over every real or imagined challenge to his integrity (his biggest beef was that he had to call Lorne Greene "Pa" rather than "Father"). Fed up with what he perceived as the series' declining quality, Roberts left Bonanza in 1966; it was explained to fans that "Adam" had left to study at a European university. Free of his TV series commitment, Roberts returned to his first love, the stage--and also divested himself of the toupee he'd been forced to wear as Adam. The actor played the straw-hat circuit in such musicals as Camelot and The King and I, all the while accepting film and TV roles that came up to his standards. Unfortunately, his stubbornness and standoffishness left a sour taste with co-workers and fans alike, and Roberts was unable to soar to the artistic heights to which he aspired. After years of declaring that he'd never again return to the grind of weekly television, Roberts accepted the role of Dr. "Trapper" John McIntyre, chief of surgery at San Francisco memorial hospital, in the seven-season (1979-86) M*A*S*H spin-off Trapper John MD. In 1991 Pernell Roberts assumed the hosting duties of the TV anthology FBI: The Untold Stories.

Trivia: The son of a Jewish movie-publicist father and an Irish Catholic musical-comedy actress, Michael Landon grew up in a predominantly Protestant New Jersey neighborhood. The social pressures brought to bear on young Michael, both at home and in the schoolyard, led to an acute bedwetting problem, which he would later dramatize (very discreetly) in the 1976 TV movie The Loneliest Runner. Determined to better his lot in life, Landon excelled in high school athletics; his prowess at javelin throwing won him a scholarship at the University of Southern California, but a torn ligament during his freshman year ended his college career. Taking a series of manual labor jobs, Landon had no real direction in life until he agreed to help a friend audition for the Warners Bros. acting school. The friend didn't get the job, but Landon did, launching a career that would eventually span nearly four decades. Michael's first film lead was in the now-legendary I Was a Teenage Werewolf (1957), widely derided at the time but later reassessed as one of the better examples of the late-'50s "drive-in horror" genre. The actor received his first good reviews for his performance as an albino in God's Little Acre. This led to his attaining the title role in 1959's The Legend of Tom Dooley, which in turn was instrumental in his being cast as Little Joe Cartwright on the popular TV western Bonanza. During his fourteen-year Bonanza stint, Landon was given the opportunity to write and direct a few episodes. He carried over these newfound skills into his next TV project, Little House on the Prairie, which ran from 1974 to 1982 (just before Little House, Landon made his TV-movie directorial bow with It's Good to Be Alive, the biopic of baseball great Roy Campanella). Landon also oversaw two spinoff series, Little House: The New Beginning (1982-83) and Father Murphy (1984). Landon kept up his career momentum with a third long-running TV series, Highway to Heaven (1984-89) wherein the actor/producer/director/writer played guardian angel Jonathan Smith. One of the most popular TV personalities of the '70s and '80s, Landon was not universally beloved by his Hollywood contemporaries, what with his dictatorial on-set behavior and his tendency to shed his wives whenever they matured past childbearing age. Still, for every detractor, there was a friend, family member or coworker who felt that Landon was the salt of the earth. In early 1991, Landon began work on his fourth TV series, Us, when he began experiencing stomach pains. In April of that same year, the actor was informed that he had inoperable pancreatic cancer. The courage and dignity with which Michael Landon lived his final months on earth resulted in a public outpouring of love, affection and support, the like of which was seldom witnessed in the cynical, self-involved '90s. Michael Landon died in his Malibu home on July 1, 1991, with his third wife Cindy at his side.

Trivia: Born Geraldine Stroock, she first appeared onstage (in a musical) at age 17, then worked in summer stock and toured with the Theater Guild in a repertory of Shakespeare productions; she later studied at the American Academy of Dramatic Arts. An intense, pretty, petite brunette, she went to Hollywood in 1947 after being signed by Warner Brothers; there she was proclaimed as a "new Hepburn" with an electrifying screen presence. Her career, however, never lived up to its promise. The quality of her pictures was low (in most of them she played ingenues), so she accepted an offer by director William Dieterle to appear in an Italian film, Volcano (1950); the film performed badly at the box office, but Brooks remained in Europe to make a few more movies. After returning to the U.S., she largely abandoned her film career in favor of TV and the stage; she received a Tony nomination for her performance in the play Brightower (1970) and several Emmy nominations for her work on TV. Later she became a skilled nature photographer; in 1975 she published Swan Watch, a book of her bird photographs with accompanying text written by her second husband, novelist-screenwriter Budd Schulberg. She died of cancer at age 51 in 1977.

Trivia: Torin Thatcher came out of a military family in India to become a top stage actor in England and a well-known character actor in international films and television. Born Torin Herbert Erskine Thatcher in Bombay, India, in 1905, he was the great-grandson and grandson of generals -- one of whom had fought with Clive -- but he planned for a quieter life; educated at Bedford School, he originally intended to become a teacher before being bitten by the acting bug. Instead, he attended the Royal Academy of Dramatic Art, and later worked in every kind of theatrical production there was, from Greek tragedy to burlesque. Thatcher made his London debut in 1927 as Tranio in a production of The Taming of the Shrew with the Old Vic Company, and he subsequently portrayed both the Ghost and Claudius in Hamlet with the same company. In the years that followed, Thatcher was in more than 50 Shakespearean productions and 20 plays by George Bernard Shaw. The outbreak of the Second World War took Thatcher into uniform, and he served for six years in the army, achieving the rank of lieutenant colonel before he returned to civilian life in 1946. In 1944, Thatcher had made his first acquaintance of the theater world in New York when he found himself on leave in the city with only ten shillings in his pocket -- he spent it sparingly and discovered that Allied servicemen, even officers, were accorded a great many perks in those days; he was also amazed and delighted when he was recognized while on his way into a play in New York by a theatergoer who was able to name virtually every movie that he'd done in England over the preceding decade. He got a firsthand look at the city's generosity and also made sure to meet a number of people associated with the New York theater scene, contacts that served him in good stead when he returned to New York in 1946, as a civilian eager to pick up his career. He starred in two plays opposite Katharine Cornell, First Born and That Lady, and portrayed Claggart in a stage adaptation of Billy Budd, but his big success was in Noel Langley and Robert Morley's Edward My Son. Thatcher had been in movies in England since 1933, in small roles, occasionally in major and important films such as Alfred Hitchcock's Young and Innocent (1937) and Michael Powell's The Spy in Black (1939); his British career had peaked with a superb performance in a small but important role in Carol Reed's The Fallen Idol (1948). After moving to the United States, however, Thatcher quickly moved up to starring and major supporting roles in Hollywood movies, beginning with Affair in Trinidad (1952). He was busy at 20th Century Fox, Universal, and Warner Bros. over the next decade, moving between their American and British units, and stood out in such hit movies as The Crimson Pirate (1952) (as the pirate Humble Bellows) and Love Is a Many-Splendored Thing (1955). Although Thatcher could play benevolent characters, his intense expression and presence and imposing physique made him more natural as a villain, and he spent his later career in an array of screen malefactors, of whom the best known was the sorcerer Sokurah in The 7th Voyage of Sinbad (1958), directed by Nathan Juran. Thatcher and Juran were close friends and the director loved to use him -- the two became a kind of double act together for a time, turning up in "The Space Trader" episode of Lost in Space, guest-starring Thatcher and directed by Juran.

Trivia: Berry Kroeger (pronounced "Kroger", not "Kreeger") got his start in network radio, where his velvety voice was heard announcing several major dramatic anthologies; he also played a variety of leading radio roles, including the heroic soldier-of-fortune The Falcon. While appearing on Broadway in Saint Joan, Kroeger was discovered by filmmaker William Wellman, who cast the actor in The Iron Curtain. This 1948 Cold-War film represented the first of many unsympathetic movie assignments for Kroeger, ranging from the smarmy Packett in director Joseph L. Lewis' Gun Crazy (1949) to the mad-scientist mentor of Bruce Dern in The Incredible Two Headed Transplant (1971). Kroeger's marked resemblance to Sydney Greenstreet served him well when he essayed a Greenstreet take-off in "Maxwell Smart, Private Eye," an Emmy-winning episode of TV's Get Smart. Most of Barry Kroeger's film characters can be summed up in a single word: slime.

Trivia: White-haired, patriarchal Canadian actor Lorne Greene attended Queen's University in pursuit of a chemical engineering degree. Amateur college theatricals whetted his appetite for the stage, and upon graduation he decided upon a performing career. He started out on radio, eventually emerging as Canada's top newscaster, designated "the voice of the CBC" (For a while, Greene managed a mail-order announcer's school; one of the "pupils" was Leslie Nielsen). Moving to New York in 1950, Greene became a stage, film and TV actor, co-starring on Broadway with Katherine Cornell in Prescott Proposals and in films with the likes of Paul Newman, Ginger Rogers and Joan Crawford, generally in villainous roles. In 1959, Greene was cast as Ben Cartwright, owner of the Ponderosa ranch and father of three headstrong sons, in TV's Bonanza. He would hold down this job until 1972; during the series' run, Greene unexpectedly became a top-ten recording artist with his hit single "Ringo." Upon the cancellation of Bonanza, Greene vowed he'd retire, but within one year he was playing a private detective on the brief TV weekly Griff. Five years later, he starred on the network sci-fier Battlestar Gallactica. Active as chairman of the National Wildlife Foundation, Greene put forth the organization's doctrine in his popular syndicated TV series Lorne Greene's Last of the Wild. His final weekly television appearance was on the 1980 adventure series Code Red. In 1987, Lorne Greene was all set to recreate Ben Cartwright for the 2-hour TV movie Bonanza: The Next Generation, but he died before shooting started and was replaced by John Ireland.

Trivia: American actor Selmer Jackson first stepped before the cameras in the 1921 silent film Supreme Passion. Silver-haired and silver-tongued, Jackson so closely resembled such dignified character players as Samuel S. Hinds and Henry O'Neill that at times it was hard to tell which actor was which -- especially when (as often happened at Warner Bros. in the 1930s) all three showed up in the same picture. During World War II, Jackson spent most of his time in uniform as naval and military officers, usually spouting declarations like "Well, men...this is it!" Selmer Jackson's final film appearance was still another uniformed role in 1960's The Gallant Hours.

Trivia: Actor Richard Collier was more a fixture in the realm of television, having made well over 1000 appearances on the small screen, but was nonetheless employed frequently for films. A native of Boston, Collier started acting as most people do, on stage in the theater circuit throughout Massachusetts. When World War II broke out, his acting career was put on hold as he served in the U.S. Army. Only after the war did Collier begin making appearances in film and the new medium of television. Some of the many television shows the actor appeared on include The Beverly Hillbillies, The Andy Griffith Show, and Batman. Collier died, at the age of 80, in early 2000.

Trivia: Actor Ted Knight dropped out of high school in order to enlist for World War II service. During the postwar years, Knight studied acting in Hartford, Connecticut. He became proficient with puppets and ventriloquism, which led to steady work as a TV kiddie-show host. Knight spent most of the 1950s and 1960s doing commercial voice-overs and essaying minor TV and movie roles (he was the nonspeaking cop who handed Norman Bates a robe at the end of Hitchcock's Psycho [1960]). Just barely making ends meet with TV guest spots and cartoon voices, Knight was rescued professionally in 1970 when he was cast in the role of vainglorious TV anchorman Ted Baxter on The Mary Tyler Moore Show. Three years into the series, Knight threatened to quit because of the one-note stupidity of his character. He was assuaged when the MTM producers "humanized" him with an understanding girlfriend (played by Georgia Engel) -- and it didn't hurt that the actor later won two Emmy awards for his portrayal of the clueless Ted Baxter. When MTM left the air in 1977, Knight attempted to headline a sitcom of his own. After a couple of false starts, he struck pay dirt in 1980 with Too Close for Comfort, playing a comic-strip artist with two nubile daughters. Too Close left the network for syndication in 1984, then matriculated into The Ted Knight Show in 1985. Though gravely ill, Ted Knight valiantly taped a years' worth of episodes before succumbing to cancer at the age of 62.

Trivia: Iowa-born Bob Hopkins started out in show business in the early '40s with a mimickry act in which his most successful impersonation was that of Bing Crosby. He turned to acting in the mid-'40s and played in every kind of movie, from brutal crime pictures like Underworld U.S.A. to costume programmers such as Son of Sinbad (portraying a slave auctioneer) over the next 15 years. Outgoing, glib-tongued, and with a ready wit, he seemed at his best portraying roles out of his own stage background, especially hosts and masters-of-ceremony, in movies such as I'll Cry Tomorrow and the late-era Bowery Boys feature Crashing Las Vegas. He also did his share of television work, in straight acting roles on The Twilight Zone and Wagon Train, but his most memorable work may have been in one excruciatingly funny episode of The Abbott & Costello Show, as a character named "Bob Hopkins," the sarcastic host of a vicious parody of Beat the Clock called "Hold That Cuckoo." Hopkins was also a songwriter, credited with the compositions "Flight to Hong Kong" and "Angel's Kiss." He died of acute leukemia shortly after completing his work in the movie Papa's Delicate Condition.

Trivia: Character actor Bill Quinn specialized in playing wise or fatherly roles on stage, screen, and television. A native of New York City, Quinn was five when he became a professional vaudevillian. After many years on stage, he joined Orson Welles' Mercury Playhouse radio troupe. Quinn made his film debut with a small supporting role in the circus drama The Flying Fontaines (1959). His film career continued steadily through the mid-'70s, then slowed down to about a film every two or three years. He made his final big-screen appearance playing the father of Dr. McCoy in Star Trek V: The Final Frontier. He appeared numerous times on television. Between 1958 and 1963, he played bartender Sweeney on The Rifleman and in All in the Family and its spin-off, Archie Bunker's Place, Quinn played barfly Mr. Van Ranesleer. His other TV credits include guest star appearances in series, miniseries, and made-for-TV movies.

Trivia: Made his debut as an actor when she was 4-years-old.Lived the first 7 years of his life traveling through Europe with his family.Was homeschooled by his mother when he was young.At the age of 8, moved to Dorset, England where he was raised.Travel through South America after graduating college.Worked renovating houses in the United States before enrolling in acting school.
