Tall, attractive actor with a long face and light, clear eyes, in mostly minor features of the 1980s and 90s. Stewart broke into films when she auditioned for, and won the lead role in, the futuristic musical, "The Apple" (1980). The film, unfortunately, turned out quite poorly, but an undaunted Stewart moved to Los Angeles and copped the role of Kayla Brady on the daytime soap, "Days of Our Lives", in 1981. Soon thereafter, she played a small role in the Sylvester Stallone vehicle "Nighthawks" (1981) and made her first TV-movie, "A Killer in the Family" (1983).
Stewart took a leave from "Days" to play a role in the sci-fi fantasy "The Last Starfighter" (1983) and left the show for good when she played the lead in "Night of the Comet" (1984). An assured sci-fi satire, the film featured Stewart as one of a group of California "valley girls" who find themselves the only people left on Earth. Later assignments almost invariably found the sensuous and eager-to-please Stewart in leading roles, but the films themselves received very little exposure or, as with the silly "Psychic" (1992), went straight to video. Sometimes the films ("World Gone Wild" 1988) were watchable genre fare and sometimes ("Dudes" 1987) they were not.
Stewart's one hit was the sleeper comedy "Weekend at Bernie's" (1989), with Stewart as Jonathan Silverman's romantic interest. She did well to stay away from the sequel, focusing much of her energy in the 90s on TV-movies including "Passion and Paradise" (1989), and "The Sea Wolf" (1993).
