Works

Guinevere Turner and I Shot Andy Warhol director Mary Harron wrote the screenplay which ended up being selected for the film version of Bret Easton Ellis' American Psycho. She has a brief cameo in the film, in which she delivers the in-joke, "I'm not a lesbian!". (Turner has publicly acknowledged her lesbianism.Interview with Guinevere Turner (page 2)).
Turner emerged on the scene with the film Go Fish, which she co-wrote and co-produced with her then-girlfriend, Rose Troche. Turner also starred in the film, portraying a young woman named Max whose friends help her find a new girlfriend, Ely, portrayed by VS Brodie. Director Kevin Smith was a fan of the movie, particularly a scene in it wherein, in an imagined sequence, some of a character's friends chastise her for "selling out" and sleeping with a man, and used it as an inspiration for his own take on a similar theme in his own film Chasing Amy. Turner has cameos in both Chasing Amy and Smith's later film Dogma; her name is used as that of Joey Lauren Adams' character in Smith's Mallrats.
