This question is obviously inspired by Sasha Grey's entrance into mainstream moviemaking in Soderbergh's "The Girlfriend Experience".
Was there a Adult actor or actress who made such a move successfully?
If so, who was the first known one?
To reject (probably numerous) unsuccesful attempts, I'm ONLY looking for the actor/actress that:
Were legitimate full time Adult ones, meaning roles in at least 2-3 movies that would reasonably be classified as Adult Movies, ideally from known studio.
After that, for a period of at least 5 years, derived their main income from mainstream movies (or TV or live theater), appearing in at least 3-5 ones.
Have not had any acting roles in Adult Movies after that.
To avoid offending people, please refrain from linking to adult-themed sites in your answers - most actors are listed on either IMDB or Wiki, I would hope; or from listing - never mind including pictures from adult movies they were in.
