The biggest gimmick in the film, apart from Steven Soderbergh's recapture of sexual themes, is the protagonist of the film, Sasha Grey. In the film she played a senior prostitute-or a "call girl". In real life, she herself is a star of pornographic movies. She entered the pornographic film industry at the age of 18. Although she is a porn star, she really likes movies, and on the list of her favorite directors, Jean-Luc Godard and other generals are on the list. In January this year, Sasha Grey won the adult Oscar for Best Actress. In an interview with AVN, she said: "I like watching movies very much, and I am very willing to work with the director to make movies. For me, there is no subject matter that is taboo and cannot be filmed. I knew Steven a long time ago. Soderbergh, I admire his work very much. I am honored to work with him. I got an adult Oscar, but Steven Soderbergh got a genuine Oscar." This is not the first film by Sasha Grey. She has previously filmed the independent movie " Quit " HD movie download and a low-cost Canadian horror film "Smash Cut". However, in those works, she can be regarded as a "friendship guest appearance" at best, and she only appeared briefly.
Regarding finding a porn star to be the lead actor in their own movie, many film critics have a lot of criticism, and they have also given titles such as "non-professional actor" to Sasha Grey. Faced with this, Steven Soderbergh said: “I don’t care if actors are professional or not-or what they want to express is'professional'. But I don’t think any actress can be more'professional' than Sasha Grey Now. What I value is her potential and the feeling she gives me in the movie. Besides, I don’t think anyone is more suitable for this role."
