According to Ain't It Coll News, it seems that actor Matthias Schweighöfer (Valkyrie) told the German edition of Gentlemen's Quarterly that he is going to have a role in Kenneth Branagh's soon to be made Thor film.

Then the actor said that Jude Law and Robert DeNiro are also attached to the project.

There isn't any word yet on what roles the actors (Schweighöfer included) will have in the film.
