This would never happen, and honestly Hollywood would probably end up butchering TES in the process. Unlike games such as Mass Effect, Uncharted, Bioshock, or any of the other games coming out with movies, TES is too wide and expansive and doesn't really have a main protagonist. Making a movie ,specifically for this installment, in TES wouldn't make any sense to anyone except the fans who have been playing TES for some time.
As far as actors to, Liam Neeson as Esbern for sure. I think Sam Worthington could probably be a decent Dovahkiin, but a number of actors could probably pull it off.
