I like Heath Ledger's pencil magic trick in Batman.

I second TS' choice about Michael Madsen in Reservoir Dogs (1 of my top 10 fav movies).

Denzel Washington played a back stabbing evil role in Training Day. I enjoyed that one too. Same way with that dude in No Country For Old Men.

But what really bothered most was a couple of role by Daniel Day Lewis. He was great in Gangs Of New York and Let there Be Blood.
