Even though it's Saturday, that doesn't mean the big news waits till Monday -- Nikki Finke over at Deadline Hollywood has once again come through on yet another Marvel casting scoop; this time it would appear as if actor Chris Hemsworth -- who played Kirk's father in the opening scenes of Star Trek -- has been cast as Thor in Marvel's big-budgeted, live-action film due out in theaters on May 20, 2011. Kenneth Branagh is set to direct, with production currently scheduled to begin early next year.

Hemsworth is a bit of a departure from the big, familiar names Marvel has been using to populate its superhero films -- but he's a solid choice; a bright, young pretty face who, like Chris Pine, seems destined to break out in the next year. Not only did he land a pretty sweet role in Trek, but he's currently shooting the horror flick The Cabin in the Woods (written by Joss Whedon, directed by Cloverfield's Drew Goddard), was just cast in the Red Dawn remake and starred on the popular Aussie show Home and Away. Hemsworth joins a production that doesn't have anyone cast as of yet, and since they're going with a relative unknown in the lead role, look for Marvel and Branagh to stick some known faces around him (Josh Hartnett has been rumored to be up for the part of villain).

What do you think of Hemsworth? Is Marvel taking a risk by casting an unknown in the lead role, or is this the best way to go when it comes to Thor, the Viking God of thunder?
