Steven Soderberghs film The Girlfriend Experience is a well acted, well made piece about a usually taboo subject matter. Shot almost documentary style with lots of hand-held action this follows a high-end call girl through her work - both clients and logistics (books, website development) and her life with her boyfriend.
Grey is surprisingly effective in this role (and was also quite charming in the Q&A afterwards) detached (deliberately) from her clients and a journalist who is trying to gather information for a piece. The film is ultimately an amalgam of stories that the team have gathered from real call girls and does end up feeling that way. Effective but not enthralling.
