Stellan Skarsgard was interviewed today, and he spilled the beans, stating that he has been cast in Thor, for a part that he can't reveal. The source isn't in English, so here it is translated:
"Stellan Skarsgård is ready for a role in action movie "Thor."
He will thus play against Hollywood star Natalie Portman.
The film, based on a comic book about the god Thor fighting criminals in today's world, is directed by Kenneth Branagh.
Everything is still secret about the script and Skarsgård can not reveal what role he will play.
'They wanted me to sign without reading the script. That I refused to do. Then they sent one to me that was so coded that I could only print one copy,' says Stellan Skarsgård to TT spectra.
Some time ago it was said that Stellan Skarsgård's son, Alexander Skarsgård, was on its way to the title role in "Thor." In the end however, it became Chris Hemworth, known from "Star Trek" who got the job.
The filming of "Thor" begins in spring 2010, with planned theatrical release in May 2011."
