Shelley was one of the most successful models of the 1970s, earning Supermodel status by the time she retired from modeling in the early 1980s. Like for many of her predecessors, it opened Hollywood doors for her with her big break as becoming one of Charlie's Angels. When she left that show, she appeared in a variety of films, TV movies and TV series; but she carefully chose the roles she would play, especially series-wise. In 1986, she had she told Entertainment Tonight, "You don't sign on the dotted line for five years unless it's something you really wanna do or you're very foolish." She lead the cast in two TV series, Cutter to Houston and Jack and Mike, which were well-received by most critics but were short-lived (sleeper hits were unheard of then). She also landed roles in theatrical releases such as Martin Scorsese's The King of Comedy, Troll and The Stepfather. She also shined in small screen releases such as Single Bars, Single Women and Bridesmaids.
