We Could Get An Older Version Of Batman In New 'Batman/Superman' Movie

Ever wanted to see an older Bruce Wayne/Batman on screen (besides George Clooney), like the ones that have been portrayed in so many comics and graphic novels?  Well, that might be the sort of Bats that we'll be seeing in Zack Snyder's Man of Steel sequel (currently untitled, but will most likely be Batman vs. Superman or visa versa).
According to several (more than 1, less than 10 *wink*) unrelated BOF sources, the new Batman that will appear in the MAN OF STEEL sequel, will be older. Like mid-40s older.
One [very] interesting name that is being thrown around is Josh Brolin -- and I absolutely love the thought.

Another thought: maybe Michael Keaton?
