There are a few movies I can note where their directors also played a role in their films:
- Orson Welles tended to star in many of his films, but that was during the 40's
- Roman Polanski played the role of the man who cut Jack Nicholson's nose in Chinatown, but Chinatown was released in 1974
- The most recent film I can think of where this happened was when Quentin Tarantino played Jimmy in Pulp Fiction, which was released in 1994
I can't really think of any recent movies where directors did this. Is it common to see directors acting in their own films these days?
