Title speaks for itself, my ranking would go like this
1) Heath Ledger as Joker (Probably my favorite acting performance ever)
2) Aaron Eckhart as Two face (Underrated IMO)
3) Anne Hathaway as Selina Kyle
4) Christian Bale in TDKR
5) Christian Bale in Begins
6) Tom Hardy as Bane
7) Gary Oldman in TDK
8) Christian Bale in TDK (Underrated)
9) JGL as John Blake
10) Micheal Cain is all 3
Gonna change it up a little after rethinking...
1) Heath Ledger as Joker in TDK
2) Aaron Eckhart as Two Face in TDK
3) Gary Oldman as Gordon in TDK
4) Anne Hathaway as Selina Kyle in TDKR (By far the best female character in the trilogy)
5) Christian Bale as Bruce/ Batman in TDKR
6) Tom Hardy as Bane in TDKR
7) Christian Bale as Bruce/ Batman in Begins
8) Gary Oldman as Gordon in TDKR
9) Tie between Micheal Cain, Micheal Cain, and Micheal Cain!
10) Christian Bale as Bruce/ Batman in TDK (Underrated)
Honorable Mentions: Morgan Freeman in TDK (Good in all 3 but TDK is his best IMO) JGL in TDKR, Neeson in Begins, Cillian in Begins, Rutgar Hauer in Begins, Maggie in TDK (Most overhated performance of the trilogy IMO), Oldman in Begins.
This is really hard because there has been so much talent in this Bat trilogy. I never would have thought a cbm trilogy would attract so much talent.
