Inside the actors' studio - Christopher Walken

Walken, talken. Enjoyable bit of quick-response questionnaire at 38:40 (and just before that an interesting comment about the importance of not knowing what's next). There's a good question at the end. Look at the other actors too. Pacino's wasn't great, but that might be because he's better as actor than interviewee.
