i'm not sure i agree - DDLewis is much more from the Method acting school - Gary Oldman is much more from the Classical (British) Acting style
the old anecdote about the Dustin Hoffman v Olivier 'clash' of acting styles on the set of Marathon Man highlights the ostensible difference
I just meant that these are two actors who usually never look the same from movie to movie. If I ran into either of them on the street, I would have no idea who they are, whereas if I saw Tom Hanks or Chris Evans, I'd recognize them instantly.
