I really wasn't even aware that Batman and Superman had this kind of grudging friendship.
I used to audition for 'NYPD Blue' quite a bit, so I had this stock New York detective character that I would bring in for all their auditions.
I think it's one of those funny things - sometimes you're not really friends with somebody until you've gotten into a good fight, and I think that's the situation with Superman and Batman.
I used to wear Clark Kent glasses, ever since I was in college. I used to have those Army-issue glasses, and they used to be those black glasses Clark Kent used to wear. And I wore those for years.
I haven't done much voice-over work, but I enjoy it. I'm hoping to do more in the future.
