Seriously? Have you actually watched the movie? The role required almost no range at all. His lines were in the single digits, or darn close to it. About the only line he uttered that took any finesse at all was; “shoot pool fast Eddie”.
How about you tell how you know it was a challenge. Fill me in on how putting on a suit coat and holding out ones hands for talc registers as an challenging performance. I can use the laugh.
Because I am an acting teacher. Have been on and off for years. In New York City - coaching opera students in the art of acting. So buzz off, amateur.
