Hobbit impersonators get big bucks, Reeves. And if they want you bad enough, they'd simply gut you off at the knees.
Off topic but the Captain America prevues look damn impressive and the Thor actor (Chris Hemsworth) should have been cast in the Conan role. He put on size for this role of Thor.
And here's the explanation I got from someone who saw SuckerPunch.....
Babydoll was actually in a home for the criminally insane but the administrators of that 'hospital' set it up as a whorehouse for the wealthy. And in an effort to maintain the little bit of 'sanity' that Babydoll still possessed, she had to develop an imaginary world.
Or something like that.
I don't think she understood it either.
