His iMDB listing doesn't have anything other than wrestling. iMDB isn't always to be trusted, but they have a pretty indepth listing of the people in Underworld, including werewolves. I never knew 0'Haire was a professional boxer *and* professional photographer, though.
You know, I noticed this as well. I went and checked out the online trailer, and I think one of the main characters looks a bit like O'Haire (he's the guy in the coffin in the trailer... which doesn't make sense since the guy in the shot phil and I are talking about is clearly a werewolf).
If Owen Hart wont be inducted how about Curt Henning or The British Bulldog. Both of these men could be seen as legitimate inductees. Even Rick Rude or Roadwarrior Hawk. I would also suggest Bob Backlund.
