Jackhammer - well done with the
Toby Kebbell reference. I've only seen two of his movies (
Dead Man's Shoes and
Rocknrolla) and the dynamics of both roles are very demonstrative of his capabilities. The same could be said for
Paddy Considine, if at least for his lead in
Dead Man's Shoes, and then he plays a British bumpkin cop in
Hot Fuzz.
The obvious choices (Depp, Pitt, Hopkins, Nicholson) already being mentioned several times, I'll go with a couple who haven't.
I'm the first to mention
Samuel L. Jackson? For shame, brethren! I know of no other actor who demonstrates such a work ethic and devotion to his craft. Again, diversity and dynamics are obvious in his countless roles.
Robert Carlyle has been great in anything I've seen him in. My favorite role definitely being that of the wandering cannibal in
Ravenous.
