At a recent press conference for Jim Sheridan's Brothers, actress Natalie Portman said that she was so intrigued when she heard that director Kenneth Branagh was directing an adaptation of Marvel Comics' Thor that she just had to be a part of it:
"I just thought it sounded like a weird idea because Kenneth Branagh's directing it, so I was just like, 'Kenneth Branagh doing 'Thor' is super-weird. I've gotta do it.'"
