So what does Hemsworth have to say about the casting rumors...
He's not exactly confirming or denying anything.
Now that that's settled, onto more important things.
So is there a superhero-sized battle of the bods brewing between the Hollywood hunks?
"I should have a picture of him!" Hemsworth laughed. "The bloke looks great. [But] if he wants a little healthy competition..."
And get this: Hemsworth's Thor costar Jaimie Alexander actually admits that she had trouble keeping her hands off his godly bod during filming.
"I have touched his pecs," she gushed. "Sometimes you'll go up to him, you'll be like, 'Chris, how are you?' And then you're like, 'I meant to shake your hand.' He could flex for me any day and I'd be totally OK with this...He's a stunning human being."
After last night's screening of the film, celebs like Liam Hemsworth, Colin Farrell and Peter Facinelli joined castmembers at the Thor premiere after party presented by Acura at Hollywood hot spot SupperClub for food, photo ops and plenty of mingling.
