Rene Russo is set to star in the comic book adaptation of Thor. The Thomas Crown Affair actress will play Frigga, the mother of the hammer-wielding Marvel superhero.

In the film, Frigga is queen of Asgard and the wife of Norse god Odin - played by Anthony Hopkins. The movie also features Chris Hemsworth as the title character, Tom Hiddleston as the villain Loki and Natalie Portman as Thor’s love interest.

Natalie, recently said that security around the movie is so tight, she struggles to read her script because it is on watermarked paper.

“I think everyone has gotten more secretive just because of the preponderance of technology that can scam just about anything,” Portman said. “It’s like you don’t get a script anymore that doesn’t have watermarks that would identify you if you ever tried to leak anything. The ‘Thor’ script is hard to read because it’s on some weird colored paper and they have your name in huge letters across every page. Marvel’s like some like crazy underground world.”

Thor is due to be released in 2011.
