In a German GQ interview with Matthias Schweighöfer (Valkyrie), the actor reportedly (we haven’t seen a copy of the issue and the news hasn’t been published online) announced he’s in the running for a role in Thor, whilst revealing that Robert De Niro and Jude Law have also been cast. The rumor was originally posted to AICN.
I’ve classified this as rumor for now, there’s no hard proof and the article might well have been mistranslated. However, both Law and De Niro have worked with Thor director Kenneth Branagh in the past, which gives some credence to the claims.
Which characters would these actors play?
In other casting news, Stan Lee has confirmed to Collider that he’ll be taking up his cameo role for Thor, though he doesn’t yet know the details.
