Kat Dennings in for Thor

Nick And Norah's Infinite Playlist and House Bunny star Kat Dennings has been cast in Kenneth Branagh's upcoming adaptation of Marvel comic-book Thor.

We know this because Natalie Portman told us yesterday ("I'm really excited. Kat Dennings is going to be in it and she's a good friend and an amazing actress.")

Portman plays Jane Foster, who nurses Thor's human alter-ego Donald Blake. So which role might Dennings be taking?

Heyuguys! ' theory is that she's playing science intern and "overt wiseass" Marcy Lewis - as the connection to science... stuff would probably put her in contact with Blake/Thor.
