It looks like Natalie Portman has been cast as Jane Foster the main female lead in Marvels Thor. She will be playing a nurse who later becomes Thor's love interest. I think that she is a great choice for this role. Just curious to how they are going to modernize her character. The movie is due out in May 2011. Chris Hemsworth has already been cast as Thor . Which he got his big break from this Summer's Blockbuster Star Trek playing George Kirk. And Tom Hiddleston will be playing the Evil Loki . source- THR
