A bat, a cat, and a bird Walken to a bar...Stop me if you've hear this one. Welcome back to BIG SCREEN BATMAN where today (okay mostly last night before I fell asleep) I watched Tim Burton and Michael Keaton's swan song (well maybe not for Mike) in the Batman world with 1992's "Batman Returns." And this time around they doubled up the villainy with Danny DeVito and Michelle Pfeiffer - oh and Christopher Walken too.
