The Iron Man sequel will debut on April 30, 2010, with Downey Jr., Gwyneth Paltrow and Terrence Howard intact, followed by the feature film debut of Thor about 5 weeks later. In the Stan Lee/Larry Lieber comic book version of this character from Nordic mythology, Thor’s alter-ego is a disabled doctor named Donald Blake, and there has been a fair amount of speculation that Marvel wants professional wrestler Triple H or Scottish actor Kevin McKidd, who made an impression in the HBO series Rome, to carry the hammer.
