Chris Hemsworth has revealed that he based the character of Thor on Mike Tyson.
The former Home & Away actor has landed the central role in Thor, just the latest Marvel Comic book character to be adapted for the big screen.
And the actor admits that he struggled with the hammer whist filming and used boxing as a way of getting to grips with the weapon.
He told About.com: It really is a very impractical kind of weapon in a sense. There's a big huge head on it and a tiny little handle.
"So we talked about boxing a lot actually. I'd done a lot of Muay Thai for years and Muay Thai is much more on your toes and legs involved.
"Boxing is more of a grounded sort of technique. We'd talk about Mike Tyson, low to the ground and power through the legs. A lot of that I think influenced Thor and certainly big open shoulders, big shoulder movements.
"It becomes a very gritty kind of street fighting stuff at times and happens to have a big old hammer in his hand as well."
And that's not the only thing that Hemsworth struggled with the actor also struggled with pretending to fall through space.
"There's something I thought I could do and I couldn't which was strapped into this harness, I had to pretend like I was falling through space. I basically was there on a couple of wires and they just spin you.
"I thought that's something that at the show grounds you pay five bucks for and it's just going to be fun. Two spins later, I was like, 'Whooooaaaaa.' We stopped and I was pale. They're like, 'You want to stop?' I was like, 'No, just keep going until I throw up.'
"Eventually we got what we needed and I just had to sit down for a couple hours. It was hideous."
Hemsworth is also set to reprise the role as part of The Avengers movie.
