Although he geared himself up for major film stardom throughout the 1950s, it took a leading role on a 1960s TV series opposite a lion and chimpanzee to make Marshall Thompson a genuine household name. Born on November 27, 1925 and named James Marshall Thompson after an ancestor, a famed Supreme Court justice, he moved with his parents from his Peoria, Illinois hometown to the Los Angeles area at age five where his father set up a successful Westwood practice in dentistry that continued for over three decades. His mother once took to the stage as a concert singer and musician. Marshall was their only child. He caught the acting bug while in high school when he appeared in a number of school productions and was spotted by a local talent agent. This did not pan out but he also acted upon his early skills as a writer. The Westwood Village Players produced the young high school student's ambitious three-act play "Faith," the story of two young aviators in a Nazi prison . He enrolled at Occidental College where he switched from pre-med to drama. He was also a member of the college's cross-country team. The athletic, lanky-framed, good-looking collegiate was re-discovered while performing as one of the Occidental Players in 1944. This time, he made good and was signed to a Universal contract. He began in minor war-era films with Reckless Age (1944) starring Gloria Jean and was quickly brought over to MGM on the strength of this film. With most big stars off to war, Marshall was given the chance to work quite steadily in perfunctory nice guy assignments such as Blonde Fever (1944), The Clock (1945), They Were Expendable (1945) and Bad Bascomb (1946) opposite Frances Rafferty . His first association with animals came with the lead in the horse-friendly yarn Gallant Bess (1946), MGM's first film produced in CineColor. The handsome Marshall went on to provide yeoman work in the war dramas Homecoming (1948), Command Decision (1948) and Battleground (1949), becoming an instant bobbysoxer idol to film fans. A genial player on screen, he managed to show potential outside his benign typecast in Dial 1119 (1950) as a cold-hearted, baby-faced killer, and finished his MGM contract out with The Tall Target (1951) playing a potential assassin of Abraham Lincoln. Freelancing for the next several years after losing his contract to MGM due to a change of management, he assisted a few serious-minded dramas but a noticeable pall soon took over his career with "B" thrillers taking up the bulk of his time. He achieved a bit of cult infamy with the films Cult of the Cobra (1955) Fiend Without a Face (1958), It! The Terror from Beyond Space (1958) and First Man Into Space (1959). A couple of notable exceptions were his strong roles in the Audie Murphy starrer To Hell and Back (1955) and the La grande caccia (1957) [East of Kilimanjaro], in which he performed his own dangerous stunts and developed a lifelong passion for Africa and wildlife. It was this aforementioned wildlife association, combined with TV, that made the biggest dramatic impact on his career. Throughout the 1950s Marshall appeared faithfully in small-screen presentations but in 1966, he was cast as a series lead, that of game warden Dr. Marsh Tracy in the African adventure "Daktari" (1966) developed by Ivan Tors and filmed at Africa, U.S.A., a wild-animal theme park near Los Angeles. Although overshadowed sometimes by those inveterate scene-stealers Clarence the Cross-eyed Lion and Judy the Chimpanzee, Marshall provided a strong, honest, authoritative yet friendly persona and earned the most attention yet in his nearly two-decade-long career. He was also involved in nearly every aspect of the show and afforded the opportunity to direct a few episodes. The series lasted five seasons and, following his departure, continued in the animal vein and his association with Tors by hosting the live action daytime series "Jambo" (1969), starring in the feature film Clarence, the Cross-Eyed Lion (1965) (which he co-wrote), and directing some episodes of "Flipper" (1964). Laying low after his final feature film Around the World Under the Sea (1966/I), which starred assorted TV adventure alumni including "Flipper" (1964) star Brian Kelly and "Sea Hunt" (1958) lead Lloyd Bridges , he spent much of his later time providing footage for wild-life documentaries. An avid photographer, horseman, and guitarist, among many other talents, he died at age 66 in 1992 of congestive heart failure and was survived by his wife Barbara Long , daughter Janet, and grandson Jackson.

Brother-in-law of Richard Long , Mara Corday and Suzan Ball .His dentist father, Laurence Thompson, was a decorated WWI medic who received shrapnel injuries during his tour of duty. Decades later, a small fragment dislodged and caused a fatal stroke. He was in his late 60s. His mother, Pauline, was a one-time concert singer. His parents met while she was entertaining WWI troops.Life-long friend of actress Betty Lynn , best known as Thelma Lou on "The Andy Griffith Show" (1960). Both graduated from University High School in Los Angeles.Unlike some sources indicate, Marshall never had any intentions on becoming a minister -- the story was promoted by MGM's publicity department; however, he was a pre-med student at Occidental College at one time before focusing on drama.First met his wife, the former Barbara Long , through Roddy McDowall and reconnected later at the Laguna Playhouse while both were appearing in the play "French Without Tears" in 1948. A year later they married and had one daughter, Janet. He subsequently appeared with his brother-in-law Richard Long in Cult of the Cobra (1955).He produced, directed and starred in A Yank in Viet-Nam (1964), a film that could have had tragic consequences. It was an on-location anti-Viet Cong picture that had the Viet Cong putting a price on his head during the shoot. The picture was important in that it was the first filmed during the war and while under fire.
