Also, the entire cast of Citizen X. Stephen Rea, Donald Sutherland, Jeffrey DeMunn, Joss Acklund...all excellent actors who turn in excellent performances.
Sutherland is also the highlight, for me, of Backdraft (another amazing cast) even though he's only in one scene. The parole-the-firebug scene.

Right around 3:20 in the clip, when De Niro pulls the doll out of the bag...that switch from "parroting what the Parole Board wants to hear" to "This is the real me" is just eerie!
And another one: Freddie Highmore from Bates Motel. I was married to someone almost as crazy as his character, and this kid's ability to just "kill-switch" all the emotion out of his face and eyes is TERRIFYING. I've seen it in person (from said ex-husband) and Highmore's got it 100%
nailed.
