I voted for Bale. I think he encorporates the current style of the comic better than the other actors although Keaton does come close.
Kilmer was ok but Clooney was a bit silly really (& the film isn't great - except for the lovely Poison Ivy <sigh>).
Adam West is the classic Batman of the old school & the film & the series from the 60's are very entertaining - they also have the best batmobile ever. Pass me the shark repellant Robin
I love the DC Batman comics & their spin-offs (Red Robin, Batgirl, Gotham City Sirens (very sexy)) & will be buying the latest German Batgirl release tomorrow (US issues 5-8 in one volume translated into German). The earliest Batman comics I have are from the early 1970's & there are reprints in them from the early issues (1940's, 1950's) which are very different from the modern comics.
