'Thor' cast sunny for Natalie Portman

The director is Kenneth Branagh. The villain is stage veteran Tom Hiddleston. And now Natalie Portman is the love interest.

Is "Thor" a comic-book movie or a Shakespeare adaptation?

Portman will join Branagh, Hiddleston and star Chris Hemsworth for Marvel Comics' version of the Norse god of thunder, according to The Hollywood Reporter. She'll play Jane Foster, in the comic books a nurse working for Dr. Donald Blake, who is secretly Thor.

No word yet on the plot or how it'll tie into Marvel's other big-screen properties, though when evil trickster-god Loki (played by Hiddleston) is around, reality tends to shudder.

Filming on "Thor" begins early next year. The movie is scheduled to hit theaters May 20, 2011.
