Russell Crowe - probably the best of the bunch

Ray Winstone - fantastic in everything I've seen him in

Matt Damon - I've never been less than impressed

Heath Ledger - the best of the younger crop

Ben Kingsley - masterful in everything he does

Jeff Bridges - in my mind, the best American film actor of the past 35 years

Clive Owens - incredible presence

Daniel Craig - see above

Paul Giamatti - never less than great

Jim Broadbent - the Alec Guinness of today


edited to add that I think Sean Penn is in a class by himself.
