Last time a movie thread came up, I said it needed a non human female mage for Dovahkiin, or it would end up with the usual musclebound cliches. I stand by that. Imagine the film they would make with a Statham or Pitt or the like as an axe wielding Nord warrior, then think what they could do with, I don't know perhaps Sigourney Weaver or Summer Glau as a Breton sorceress (those two know how to kick ass as well, don't forget).
My favorite asskicking actress is Famke Janssen.. I mean, she made James Bond look stupid.
Of course, she doesn't exactly fit a Nord look either, despite being 6'0"
