He thinks Luke would be all hermit like and spiritual. He says he hasn't bothered with the EU material, and I think that's smart. Wars EU and Trek EU are very much alike in that they get bleaker and bleaker.
He asked his wife if Luke should have a beard and she vetoed it. I find that hilarious.
He also talks about being the joker in Batman: The Animated Series, which I thought was awesome.
He also thinks that Luke would rely more on stealth than aggression. That's interesting as the EU has him running around glowing. Yeah. Seriously, Glowing.
He said if he had to fight Batman as Luke, he'd stick to the shadows and try using mind trick.
The reddit standard - Would you rather fight one horse sized duck or 100 duck sized horses was modified for Hamill, he got one AT-AT sized ewok or 100 ewok sized AT-ATs. He chose the giant ewok.
