I was watching "The Comedy Store" documentary a month or so ago and he pops up a few times in it. I had somehow gone this whole time not realizing he started out as a stand up comedian. I knew he did comedies to start out but really had no clue.
Mr Mom, Johhny Dangerously and Gung Ho to name a few of my favorites... But when he did such a good job in Batman, it got him out of that Stereotyped role and he really took off, IMO
