I can't take Adam West seriously as a result of Family Guy.
But no, Adam West is older than Michael Caine and Morgan Freeman and both of them are "walk and talk actors" now. So i can't see what Adam West would do that the other two didn't.
Didn't you see Morgan Freeman jump up that ladder? The man has some action films in him yet.
Now look what you have done, you made me quote myself. Did I really have to explain the joke? If you actually saw the movie, Morgan Freeman barely made it on to the ladder let alone up it. His pace going to that ladder would be called a walking. For all three, their action days are well behind them. You just had to go and ruin a good joke TJ.
As for old guy who could do Batman, the only real contender to Clint Eastwood just because of the level of fitness he still maintains at his age. The man is like an actor sent back from the future to make us all look bad. Also Liam Nesson could do it just coming from the Taken.
As for a reboot or sequel, I do not envy the person who has to do it besides the paycheck they would be getting. Those are so seriously massive shoes to fill. We were very lucky to get a trilogy this good out of Hollywood. I can only see any attempts to capture that same lighting in a bottle end in failure.
