I have been trying to remember the name of a movie, made probably in the last 10-15 years.
The plot, set in Hollywood, is about a director who is filming a movie where the main actor is not aware that he (or she, I can't remember) is the main actor of the movie. He is not even aware that he participates in the movie. Most of the crew is also unaware of this.
The movie goes on the director hiding this from the crew and creating situations where he can film the unknowingly actor in situations appropriate for his story.
Anyone knows this movie?
