To stay fit, the Hulk punches the guy from Willow 10 times every morning

In an interview with Variety Friday, Marvel studios head Kevin Feige revealed that not only will we get to hear the Hulk speak in the new film, he will be voiced by original Hulk/deaf guy/bodybuilder Lou Ferrigno.

Variety: Do I finally get to hear a good "Hulk smash!" or what?
Feige: Yes. After five TV seasons, several TV movies and the first feature, Hulk will speak. (Yeah, he had a line in the Ang Lee film, but it was a dream.)
Hulk’s verbal skills and intelligence have varied in the comics, but he’s never been as mute as the TV version. So it’s a little ironic that TV Hulk Lou Ferrigno will give voice to the Hulk in this film.
Producer Gale Ann Hurd says Ferrigno was a last-minute addition to a panel on the movie at New York’s Comic-Con. Director Leterrier invited him to "audition" onstage.
"Lou did this amazing, ‘Hulk smash!’ " says Hurd. "And (director Louis Leterrier) said, ‘Come in, we’ll record you next week.’ Everybody thought it was either a staged event or we wouldn’t really do it. But the next week Lou came in in L.A. and his voice is the voice of the Hulk." [Source]

So a deaf guy is good at saying “Hulk smash!”, big whoop.  I’ve seen a gorilla do sign language.  Which is more amazing?  I don’t know, but I say we settle this via thunderdome.
