While he hasn't been cast yet, it seems Kevin McKidd is certainly eager to pick up that hammer. IGN ran into McKidd at the premiere of Punisher: War Zone, and he said he's still in the running for the lead role in Thor.
McKidd, who starred in Journeyman, Rome and currently appears in Grey's Anatomy, did add that there was "some back and forth" regarding the project, but was excited about the film now that Kenneth Brannagh has been attached to direct.
Marvel is eyeing up a July 16, 2010 release date for Thor. We'll certainly keep you updated on any developments surrounding this film.
