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: The odyssey of Dennis Hopper was one of Hollywood's longest, strangest trips. A onetime teen performer, he went through a series of career metamorphoses -- studio pariah, rebel filmmaker, drug casualty, and comeback kid -- before finally settling comfortably into the role of character actor par excellence, with a rogues' gallery of killers and freaks unmatched in psychotic intensity and demented glee. Along the way, Hopper defined a generation, documenting the shining hopes and bitter disappointments of the hippie counterculture and bringing their message to movie screens everywhere. By extension, he spearheaded a revolt in the motion picture industry, forcing the studio establishment to acknowledge a youth market they'd long done their best to deny. Born May 17, 1936 in Dodge City, Kansas, Hopper began acting during his teen years, and made his professional debut on the TV series Medic. In 1955 he made a legendary collaboration with the director Nicholas Ray in the classic Rebel Without a Cause, appearing as a young tough opposite James Dean. Hopper and Dean became close friends during filming, and also worked together on 1956's Giant. After Dean's tragic death, it was often remarked that Hopper attempted to fill his friend's shoes by borrowing much of his persona, absorbing the late icon's famously defiant attitude and becoming so temperamental that his once-bright career quickly began to wane. Seeking roles far removed from the stereotypical 'troubled teens' which previously dotted his resume, Hopper began training with the Actors Studio. However, on the set of Henry Hathaway's From Hell to Texas he so incensed cast and crew with his insistence upon multiple takes for his improvisational techniques -- the reshoots sometimes numbering upwards of 100 -- that he found himself a Hollywood exile. He spent much of the next decade mired in "B"-movies, if he was lucky enough to work at all. Producers considered him such a risk that upon completing 1960's Key Witness he did not reappear on-screen for another three years. With a noteworthy role in Hathaway's 1965 John Wayne western The Sons of Katie Elder, Hopper made tentative steps towards a comeback. He then appeared in a number of psychedelic films, including 1967's The Trip and the following year's Monkees feature Head, and earned a new audience among anti-establishment viewers.With friends Peter Fonda and Jack Nicholson in front of the camera, Hopper decided to direct his own movie, and secured over $400,000 in financing to begin filming a screenplay written by novelist Terry Southern. The result was 1969's Easy Rider, a sprawling, drug-fueled journey through an America torn apart by the conflict in Vietnam. Initially rejected by producer Roger Corman, the film became a countercultural touchstone, grossing millions at the box office and proving to Hollywood executives that the ever-expanding youth market and their considerable spending capital would indeed react to films targeted to their issues and concerns, spawning a cottage industry of like-minded films. Long a pariah, Hopper was suddenly hailed as a major new filmmaker, and his success became so great that in 1971 he appeared in an autobiographical documentary, American Dreamer, exploring his life and times.The true follow-up to Easy Rider, however, was 1971's The Last Movie, an excessive, self-indulgent mess that, while acclaimed by jurors at the Venice Film Festival, was otherwise savaged by critics and snubbed by audiences. Once again Hopper was left picking up the pieces of his career; he appeared only sporadically in films throughout the 1970s, most of them made well outside of Hollywood. His personal life a shambles -- his marriage to singer/actress Michelle Phillips lasted just eight days -- Hopper spent much of the decade in a haze, earning a notorious reputation as an unhinged wild man. An appearance as a disturbed photojournalist in Francis Ford Coppola's Apocalypse Now did little to repair most perceptions of his sanity. Then in 1980, Hopper traveled to Canada to appear in a small film titled Out of the Blue. At the outset of the production he was also asked to take over as director, and to the surprise of many, the picture appeared on schedule and to decent reviews. Slowly he began to restake his territory in American films, accepting roles in diverse fare ranging from 1983's teen drama Rumble Fish to the 1985 comedy My Science Project. In 1986 Hopper returned to prominence with a vengeance. His role as the feral, psychopathic Frank Booth in David Lynch's masterpiece Blue Velvet was among the most stunning supporting turns in recent memory, while his touching performance as an alcoholic assistant coach in the basketball drama Hoosiers earned an Academy Award nomination. While acclaimed turns in subsequent films like 1987's The River's Edge threatened to typecast Hopper, there was no doubting his return to Hollywood's hot list, and in 1988 he directed Colors, a charged police drama starring Sean Penn and Robert Duvall. While subsequent directorial efforts like 1989's Chattahoochee and 1990's film noir The Hot Spot failed to create the same kind of box office returns as Easy Rider over two decades earlier, his improbable comeback continued throughout the 1990s with roles in such acclaimed, quirky films as 1993's True Romance and 1996's Basquiat. Hopper was also the villain-du-jour in a number of Hollywood blockbusters, including 1994's Speed and the following year's Waterworld, and was even a pitchman for Nike athletic wear. He also did a number of largely forgettable films such asRon Howard's EdTV (1999). In addition, he also played writer and Beat extraordinaire William S. Burroughs in a 1999 documentary called The Source with Johnny Depp as Jack Kerouac and John Turturro as Allen Ginsberg. In 1997 Hopper was awarded the distinction of appearing 87th in Empire Magazine's list of "The Top 100 Movie Stars of All Time."Hopper contracted prostate cancer in the early 2000s, and died of related complications in Venice, CA, in late May 2010. He was 74 years old.

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: 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: 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: American character actor Jim Boles has also worked as a voice artist and is known for his impersonations of Abraham Lincoln.
