Hello to everyone, I don't remember the title of a film, in wich a friend of the main character tries to paint paintings similar to famous authors' paintings, and the main character sells them. Once he was selling paintings in a castle, he has been uncovered and there is a homicide. I don't remember much about this film, but I hope that someone could help me. :) The film is quite modern, maximum twelve years old I think.

Incognito (http://www.imdb.com/title/tt0119365/)?
