Batman - 1943 - Serial version time forgot.
Batman - 1966 - Adam West version. My favorite two scenes are when they are tied to a bouy and a missle is racing towards the dynamic duo. Certain death and doom! Then suddenly they are driving away safely in the Batmobile and Robin says "Thank goodness that dolphin jumped infront of us and gave its life to save us!" Nevermind how they got down. Next there is a bomb that is going to explode on a crowded beach with a short fuse. It's actually a round black bomb with a short fuse. Batman must carry that thing for two minutes looking for an area on the beach that isn't crowded, and eventually he says "Some days you just can't find a place to get rid of a bomb!"
Batman - 1989 - Tim Burton version that was called the movie of the decade. It's barely watchable today due to poor pacing.
Batman Returns - 1992 - If nothing else, Danny was good as the Penguin.
Batman: Mask of the Phantasm - 1993 - Paul Dini may have made the best Batman. The cartoon Batman movies are far better than the Schumacker movies.
Batman Forever - 1995 - Not horrible, though silly.
Batman & Robin - 1997- Nipples and cod pieces were added.
Batman & Mr. Freeze: SubZero - 1998 - Not as good as Mask of the Phantom, but again far better than the big budget Schumacker movies.
The Batman/Superman Movie - 1998 - This made me a sad, sad panda. Why ruin Paul Dini's great cartoon?
Batman Beyond: The Movie - 1999 - A futuristic take on Batman
Batman Beyond: Return of the Joker - 2001 - Never saw it.
Batman Begins - 2005 - Return to glory.
I think that makes 12.
