I'm not an Aaron Eckhart fan, but the man did a fantastic job in TDK. I don't think he's getting nearly enough recognition because everyone's attention goes straight to Heath Ledger/The Joker.

Eckhart was an AMAZING Harvey Dent/Two-Face, though.

Everyone did very well in that movie. I have a special fondness for Gary Oldman's Comissioner Gordon (maybe that's just because I have a long-standing fondness for Comissioner Gordon as it is. :P)
