Stellan Skarsgård’s son, Alexander, was originally considered as a strong candidate for the Thor role, but in the end lost out to Star Trek man Chris Hemsworth. Swedish site Ystads Allehanda report that Stellan has been cast in the movie, but his role is deeply secretive. So secretive in fact, the studio wanted the actor to sign without reading the script; he refused until he received a copy (albeit an encoded version).
