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: Karen Grassle entered the University of California-Berkeley as an English major, but active participation in school plays led her to change her field of interest and to graduate with a BA in drama. Supporting herself with menial jobs, Grassle went on to study in a San Francisco acting workshop, then went to London's Royal Academy of Dramatic Art on a Fulbright scholarship. After acting in regional repertory, Grassle received her first New York break in the 1968 play The Gingham Tree...which lasted all of five performances, but which led to steadier engagements with producer Joseph Papp and several Manhattan-based TV soap operas. Hoping to boost her career, Grassle briefly changed her professional name to Kay Dillinger, claiming to be the illegitimate offspring of the notorious 1930s bank robber (who died ten years before Karen was born!) When she came to LA in 1973 for a never-completed movie project, she was calling herself Gabriel Tree, and it was under this name that she beat out 47 other actresses for the role of Caroline Ingalls in the long-running TV drama Little House on the Prairie (co-star Michael Landon convinced her to revert to her given name). During the nine-year run of Little House, Karen Grassle frequently groused about the limitations of her role, but in recent years she has been seen on TV commercials, warmly endorsing a videotaped collection of the best Little House on the Prairie episodes.

Trivia: Actress Melissa Gilbert literally grew up before our eyes in the role of Laura Ingalls on the TV series Little House on the Prairie. A professional from the age of 3, Gilbert was ten years old when she assumed the role of Laura, and in her mid-20s when Little House branched off into a handful of TV movies in the 1980s. Outside of this series, Gilbert was the uncrowned queen of the TV remakes: She starred as young Helen Keller in 1979's The Miracle Worker, played the title role in 1980's The Diary of Anne Frank, and assumed the old Natalie Wood role in 1981's Splendor in the Grass. More recently, she has been showing up in made-for-TV biopics, e.g. Babymaker: The Dr. Cecil Jacobson Story (1993) and Against Her Will: The Carrie Buck Story (1994). Gilbert's latter-day series-TV work has included the parts of Kate Delany in Sweet Justice and Rochelle in Stand By Your Man; she has also been heard as the voice of Barbara Gordon, aka Batgirl, in the daily Batman: The Animated Series. In all of these, she has been billed under her married name of Gilbert-Brinkman (her marriage to Bo Brinkman has since dissolved). Melissa Gilbert is the sister of Sara Gilbert, who played Darlene on TV's Roseanne; her grandfather, Harry Crane, was one of the creators of the Jackie Gleason series The Honeymooners.Though she continued to work, often in TV movies, her career took a shift when she got deeply involved with the Screen Actors Guild, eventually being elected as president of the organization and serving in that capacity from 2001-2005.

Trivia: A ballet student since grade school, Melissa Sue Anderson was 11 years old when she career-shifted from dancer to actress in the 1974 TV pilot film Little House on The Prairie. For the next nine seasons, Melissa Sue co-starred on the Little House series proper as the Ingalls family's eldest daughter Mary. During this period, she won an Emmy for her performance in "Which Mother Is Mine?", a 1979 ABC Afternoon Special offering. To avoid confusion with Little House co-star Melissa Gilbert, Ms. Anderson was tagged with the nickname "Missy," a cognomen that has stuck to this day. As a youngster, Melissa Sue Anderson expressed a desire to become a film director; as an adult, she remained an actress, appearing in such efforts as An Innocent Love (1982), First Affair (1983) and Chattanooga Choo Choo (1984).

Trivia: Sidney Greenbush is a familiar name to fans of the period series Little House on the Prairie. She and her twin sister Lindsay Greenbush both played the role of Carrie Ingalls on the series, beginning in 1974, when they were just four years old. They stuck with the series until 1982, when they both retired from acting.

Trivia: The son of a movie stunt man, Victor French made his screen entree in westerns, where his unkempt beard and scowling countenance made him a perfect heavy. He carried over his robbin' and rustlin' activities into television, making multiple appearances on such series as Gunsmoke and Bonanza. It was former Bonanza star Michael Landon, a great friend of French's, who "humanized" the veteran screen villain with the role of farmer Isiah Edwards in the weekly TV drama Little House on the Prairie. French temporarily left Little House in 1977 to star in his own sitcom, Carter Country, in which he played an affable Southern sheriff who tried his best to accommodate the ever-changing racial relationships of the 1970s. In 1984, Landon cast French as ex-cop Michael Gordon, whose bitterness at the world was softened by the presence of a guardian angel (Landon), in the popular TV series Highway to Heaven. French directed every third episode of this series, extending his directorial activities to the Los Angeles theatre scene, where he won a Critics Circle award for his staging of 12 Angry Men. In contrast to his earlier bad-guy roles, French went out of his way in the 1980s to avoid parts that required him to exhibit cruelty or inhumanity. Victor French died in 1989, shortly after completing work on the final season of Highway to Heaven.

Trivia: Born, raised, and educated in the Midwest, character actress Bonnie Bartlett moved to New York City with her actor husband, William Daniels (otherwise known as the voice of K.I.T.T. on Knight Rider). During the '50s, she played Vanessa Raven on the CBS soap opera Love of Life. After adopting two children in the '60s, she went on to a prolific career on television. From 1974-1977 she played widow Grace Snider who married the farmer Isaiah Edwards on Little House on the Prairie. From 1982-1988 she played Ellen, the wife of Dr. Mark Craig (played by husband Daniels) on St. Elsewhere. At the 1986 Emmy awards, the couple became the first married team to win acting awards on the same night. Of her many made-for-television movies and miniseries, she had starring roles in Right to Die, Victim of Love: The Shannon Mohr Story, and Tuesdays With Morrie. Her supporting roles in feature films include Twins, Dave, and Primary Colors. Back on television in the late '90s, she played several reoccurring characters, most notably Lucille on Home Improvement, Dean Bolander on Boy Meets World, and Barbara Brooks on Once and Again.

Trivia: In films from the mid-'60s, American actor Richard Bull was seen in The Satan Bug (1965), The Thomas Crown Affair (1968), Secret Life of an American Wife (1969), Newman's Law (1971), and several other major Hollywood productions. Many of these roles were bits or atmosphere characters: guards, policemen, and the like. Television afforded Bull larger character roles, especially in the sitcom field. Within a ten-year period (1964-1974), he guested on Gidget, Family Affair, Gomer Pyle, USMC, The Andy Griffith Show, My 3 Sons, Room 222, and Bewitched (as pilgrim John Alden in a "flashback" episode). He also had a recurring role as a ship's doctor on the mid-'60s fantasy weekly Voyage to the Bottom of the Sea. From 1974 through 1982, Richard Bull played store proprietor Nels Oleson, the even-tempered, long-suffering husband of overbearing Harriet Oleson on Little House on the Prairie. Bull continued to appear in films and episodes of TV shows until his death in 2014 at age 89.

Trivia: Kevin Hagen is a veteran character actor long associated with intense dramatic roles. He has portrayed everything from hitmen and rapists to prosecutors and police officers, but is perhaps best known to television audiences for his portrayal of the avuncular Dr. Baker on the long-running series Little House on the Prairie. Hagen was born and raised in and around Chicago, but moved to Portland, OR, during his teens. Following a two-year hitch in the United States Navy, he attended college on the G.I. Bill, majoring in international relations, and later worked for the U.S. State Department in Germany. Bored with that job, he considered a career in law but dropped out after one year. While trying to figure out what he wanted to do for a career, he auditioned for a production of the play Blind Alley and won a small role, despite the fact that he had never acted before. Within a year, Hagen had moved up to playing the lead in a production of James Thurber's play The Male Animal, and spent the next few years scraping out a living in small theatrical productions around Los Angeles in between studying with Agnes Moorehead, among other notables. His breakthrough came with his portrayal of stern patriarch Ephraim Cabot in a production of Eugene O'Neill's Desire Under the Elms -- that led to his getting an agent and, in turn, led to his television debut in an episode of Dragnet. He appeared in various dramatic anthology shows and played important guest-star parts on programs such as Gunsmoke, Rawhide, Cheyenne, M-Squad, and The Untouchables -- in one episode of the latter, "Stranglehold," Hagen brought a startling degree of humanity and depth to the part of a professional killer. Hagen made his feature-film debut in 1958 in the Disney-produced The Light in the Forest, and that same year, he got his first regular role in a series when he was cast in the part of John Colton, the city administrator of post-Civil War New Orleans, in Yancy Derringer. The show only ran for one season, but Hagen had more work than ever following the conclusion of filming, on such series as Bonanza, Perry Mason, The Man From U.N.C.L.E., The Felony Squad, and Mission: Impossible. He also did some film work, most notably in Andrew V. McLaglen's Civil War drama Shenandoah (1965), in which Hagen played the scavenging deserter who murders James Stewart's son (Patrick Wayne) and rapes and murders Stewart's daughter-in-law (Katharine Ross). During this period, he also began a string of appearances in television series produced by Irwin Allen, guest starring in episodes of Lost in Space, Voyage to the Bottom of the Sea, and Time Tunnel. Those roles led to Hagen's being cast as Inspector Kobick, the security officer pursuing the diminutive earthlings, in Allen's Land of the Giants. He brought a great deal of humanity and complexity to his portrayal of the character in the course of the series' two-season run. During the 1970s, Hagen made frequent guest appearances on series such as M*A*S*H, Quincy, and Knot's Landing. In 1974, Hagen was cast in the role for which he has become best known, as Dr. Baker in Little House on the Prairie. He portrayed the part for ten seasons and developed a serious fandom among the series' legions of viewers. Hagen left Hollywood for Oregon in the early '80s, and has continued his work in regional theater productions of such plays as West Side Story, Follies, and Oklahoma! He also performs his own one-man show, a mixture of songs, monologues, and prairie wit and wisdom drawn from his Little House persona.

Trivia: One of the most prolific of the "Who IS that?"school of character actors, Dabbs Greer has been playing small-town doctors, bankers, merchants, druggists, mayors and ministers since at least 1950. His purse-lipped countenance and Midwestern twang was equally effective in taciturn villainous roles. Essentially a bit player in films of the 1950s (Diplomatic Courier, Deadline USA, Living It Up), Greer was given more screen time than usual as a New York detective in House of Wax (1953), while his surface normality served as excellent contrast to the extraterrestrial goings-on in Invasion of the Body Snatchers (1956) and It! The Terror from Beyond Space. A television actor since the dawn of the cathode-tube era, Greer has shown up in hundreds of TV supporting roles, including the "origin" episode of the original Superman series, in which he played the dangling dirigible worker rescued in mid-air by the Man of Steel. Greer also played the recurring roles of storekeeper Mr. Jones on Gunsmoke (1955-60) and Reverend Robert Alden on Little House on the Prairie (1974-83). Showing no signs of slowing down, Dabbs Greer continued accepting roles in such films as Two Moon Junction (1988) and Pacific Heights (1990) into the '90s. He died following a battle with kidney and heart disease, on April 28, 2007, not quite a month after his 90th birthday.

Trivia: Prior to his career as an actor, many knew Merlin Olsen as a professional football player with the Los Angeles Rams in the 1960s and '70s. After retiring from the NFL in 1976, Olsen embarked on a successful career as an actor and on-air personality, joining the cast of the popular series Little House on the Prairie and Father Murphy. He would also act as pitchman for FTD and El Paseo Bank, in addition to hosting numerous Children's Miracle Network telethons. Olsen passed away in March 2010 at the age of 69.

Trivia: Patrick Laborteaux is primarily known for his television work on the popular series Little House on the Prairie, on which he appeared with his brother, Matthew Laborteaux.

Trivia: Lead actor Dean Butler appeared onscreen from the '80s.

Trivia: The younger brother of Family Ties star Justine Bateman, actor Jason Bateman has been a mainstay on television since the 1980s, starring in countless sitcoms of varying success. He first displayed his scene-stealing propensity in the role of young sharpster Derek Taylor, best friend of star Ricky Schroder, on Silver Spoons. The audience response to Bateman was so positive that the 15-year-old was given his own sitcom vehicle in 1984, as "teenaged con man" Matthew Burton on It's Your Move. When this series was cancelled after one season, Bateman moved to the long-running role of wise-guy teen David Hogan on the mid-1980s series Valerie, which of course later changed names (and leading actresses) to emerge as The Hogan Family. During this period, Bateman also found time to star or co-star in a handful of feature films, such as the 1985 made-for-TV summer-camp comedy Poison Ivy, Teen Wolf, Too, and 1991's Necessary Roughness. However, none of the projects were successful enough to give Bateman a springboard to bigscreen stardom.Following the conclusion of The Hogan Family in 1991, Bateman embarked on a decade plagued by failed TV outings. On top of several pilots that never even saw the light of day, he was the lead in no less than four ill-fated sitcoms, Simon, George and Leo, Chicago Sons, and Some of My Best Friends. Fortunately, as the new millenium was ushered in, things started to look bright for Bateman. After a supporting turn in the Cameron Diaz comedy The Sweetest Thing, his first major theatrical feature in a decade, he was tapped to lead the eclectic ansemble cast of the Ron Howard-produced Fox sitcom Arrested Development. Acclaimed for its smart humor and fresh concept, the show became a hit with critics and viewers.In the wake of Arrested Development's success, Bateman continued to increase his presence in the world of comedy, but henceforth on the silver screen. He made memorable appearances in 2004 comedies like Starsky and Hutch and Dodgeball: A True Underdog Story, as well as more serious fare, like the 2007 Iraq War movie The Kingdom, but Bateman's next major hit seemed to come later that year, with a memorable supporting role in the comedy Juno. He would continue to be a mainstay in comedy, however, with appearances in Forgetting Sarah Marshall, The Invention of Lying, Extract, Couples Retreat, and The Switch, but the actor would continue to surprise audiences with more dramatic films as well, like 2009's State of Play and Up in the Air. For comedy fans, Bateman couldn't be avoided in 2011, with roles in Horrible Bosses as well as The Change-Up. Soon, he was signing up to star alongside Olivia Wilde and Billy Cruddup in The Longest Week, and Alexander Skarsgard in Disconnect.
