Shelley was a certified Supermodel by the mid-1970s and was known all over the world as THE Charlie Girl, Revlon's Superstar Model. So it was not surprising that Hollywood eventually came knocking on her door. Shelley's acting debut was a memorable bit role as a vacuous WASP in the 1977 Academy Award winning Woody Allen film Annie Hall. In 1978, she got her first leading lady role in the film If Ever I See You Again (which spawned the hit Roberta Flack single of the same title). Shelley was also under consideration for the role of Holly Goodhead in the James Bond film Moonraker, but the part eventually went to Lois Chiles. 1979 bought Shelley a guest-starring role in the TV series, Married: the First Year and a voice over part in the feature film, Time After Time, which was directed by her then boyfriend Nicholas Meyer. She also snagged the lead in the TV movie Death Car On The Freeway. But it was her casting as Tiffany Welles in the hit TV series Charlie's Angels that made Shelley a Hollywood Superstar.
