 Born on October 27, 1913 in Atlanta, Georgia, Mallinson would begin his acting career after signing a contract with Warner Brothers in 1945.
 That year he would have a small role in the film, "Pride of the Marines", starring John Garfield and Eleanor Powell.
 Mallinson would continue making films through the 1940s, and throughout the 1950s, appearing in over 90 films during this period.
 Notable films in which he would perform include: a featured role in the 1947 film noir "Dark Passage", starring Humphrey Bogart and Lauren Bacall; "Mighty Joe Young" (1949); the Abbott and Costello vehicle, "Abbott and Costello Meet the Invisible Man" (1951); the 1952 western, "Springfield Rifle", starring Gary Cooper; and Howard Hawks' 1952 film, "The Big Sky", which stars Kirk Douglas, Dewey Martin, and Elizabeth Threatt.
 In the early 1950s, he also had a featured role in the film serial, "Blackhawk".
 His final performance in the film industry would be in the western, "Westbound" (1959), starring Randolph Scott and Virginia Mayo.
 During the 1960s, his career diminished, and he would only make a handful of guest appearances on several television series during the decade, including performances on "Cheyenne" and "Mannix".

 He did stunt-double work for several years before breaking into acting through the good offices of John Ford.
 Tall and laconic, Johnson brought further authenticity to many roles in Westerns with his extraordinary horsemanship.
 An elegiac portrayal of a former cowboy theatre owner in the 1950s coming-of-age drama, "The Last Picture Show", won Johnson the 1971 Academy Award for Best Supporting Actor and the BAFTA Award for Best Supporting Actor.
