By "physical acting" I assume you mean conveying their character through body language (but I'm not sure).

Heath Ledger I agree with, not familiar enough with the others though. Except I'd disagree with Nicolas Cage (though you have a point about leaving Las Vegas).

I think one of the best is actually Hugh Laurie. He uses subtle gestures (as opposed to angry hulk characters or slapstick) which is far harder to pull off. Watch him play House, he's constantly aware of his injured leg, and does it in a realistic, not an over-the-top way I'd normally expect from hollywood. He plays with his ball when people are talking to him, slightly slumped shoulders, face, eyes, etc. all convey his character's miserableness or superiority complex or intelligence.

You might think he's normally like that or something and that not much of it is acting, well then go watch him in something like Stuart Little where he basically plays the opposite type of character.

I'd also add Johnny Depp to the list of good physical actors.
