Are Jude Law and Robert DeNiro aboard THOR? Seems like they are, but as who?

Hey folks, Harry here with the latest bit of Superhero Film Casting News and it is very strange indeed. According to actor, Matthias Schweighöfer, who you may have seen in VALKYRIE or RED BARON - in an article in the German edition of Gentlemen's Quarterly aka GQ, he states that he's in the running for a role in Branagh's THOR, but he also mentions that Jude Law and Robert DeNiro have joined the cast. Now, I don't doubt that they have, they're very much the sort of Actor I would expect from a Kenneth Branagh helmed THOR film, I'm just absolutely flummoxed to think who they are playing. I have to give thanks to our German reader, "I SAY THEE FUCKING KA-JAY!" for giving me the heads up on the article. And for that matter, who would Matthias Schweighöfer play? Interesting times as these Superhero films rush to begin shooting soon!
