Film Best Performances based on real FAMOUS people.
Post your five favorite performances where an actor played a real life famous person.
Rate according to the performance, not the movie itself. (For instance, Leo's performance in J. Edgar was killer even though the movie itself wasn't all that great.)
Do NOT put biopics of ordinary people (Dallas Buyer's Club etc). Because playing someone people already know is more challenging.
Props to everyone who posts by the rules.
