After experience as a model and off-Broadway actress, curvaceous Tanya Roberts began appearing in film roles that relied almost exclusively on his physical attributes. In 1979's Tourist Trap, for example, the camera took a near-fetishist interest in her long and well-toned legs. Even in her big-budget movie appearances, her acting was not her strong suit, nor was it expected to be, especially in such escapist fare as Beastmaster (1982) and Sheena, Queen of the Jungle (1984).
In 1980, Roberts was hired to play streetwise Julie Rogers, the last of a long line of replacement actresses in TV's Charlie's Angels (she was replacing the recently departed Shelley Hack). After her single Angels season, Roberts went back to movies, primarily horror films and high-class, soft-focus erotica. Tanya Roberts exhibited an engaging flair for self-parody as luscious secretary Velda in the made-for-TV Mike Hammer: Murder Me, Murder You (1983); but when time came to develop the film into a series, Roberts had other commitments, and was replaced by Lindsay Bloom. ~ Hal Erickson, All Movie Guide.
