First of all, I didn't ever think Sean Penn could out perform his role in Mystic River for which he won the oscar for and is one of my favorite movies. But he took his role in this film to a different level and couldn't have been done any better by anyone else. Mel Gibson's role was just as powerful and I don't think anyone could have done it better than him and goes to prove that Mel can still play a leading role and still be considered at the top of the list to make a memorable movie. Sean Penn will definitely be a contender to win another oscar and in my opinion, he should win it again because I highly doubt he'll be surpassed this year by another actor. This year's oscar belongs to him hands down. The Professor and the Madman is a remarkable story of history that deserves to be told and rewarded.
