Sometimes I watch movies & an actor's performance is so fantastic it leaves me speechless. This is usually the case with most of De Niro's movies (except of course his more recent 'lighter' roles, Meet The Fockers.. etc.)
Anyway these are the ones that stand out for me;
Robert Downey Jr - Chaplin
Sharon Stone - Casino
Ray Liotta - Goodfellas
Joe Pesci - Goodfellas
Lorraine Braco - Goodfellas
Matt Damon - Good Will Hunting
Uma Thurman - Kill Bill 1/2
Tom Hanks - Philidelphia & Saving Private Ryan
Leo Dicaprio - This Boy's Life
Daniel Day Lewis - The Gangs of New York
Jack Nicholson - The Pledge
There are loaRAB more but these ones spring to mind off the top of my head
What about everybody else?
