Geoffrey Rush as Peter Sellers

Geoffrey Rush playing Peter Sellers himself, and Peter Sellers playing his movie characters, has here one of the best acting performance I have ever seen, if not the best one. Rush captures Peter Sellers perfectly, and Sellers' characters he plays are absolutely believable and delightful to watch. I can fully understand why at first Rush thought he had not had "mental capacity" (or whatever words he used to justify initial turn down of this role) - it is not a small feat. I am close to considering it at least equal achievement to Peter Sellers' playing characters in Dr Strangelove.
Life and Death of Peter Sellers is a great movie, though a sad one. It is one of movies that I can watch over and over if only because Geoffrey Rush is in it.
