You can do Top 3, Top 5, Top 11 - whatever.
Although I will specify this is ONLY live-action movies. We all know Kevin Conroy is the best Batman and hell, I'd even put Will Friedle's Terry McGinnis up there, but I want to see opinions on the aforementioned live-action movies.
I dunno if this is necessarily my list but a few names that might not be considered without helping people remember....
Brendon Lee's The Crew
Michael Gough's Alfred
Aaron Eckhart's Two-Face. Best part of TDK.
Mickey Rourke as Marv
