It looks like Armie Hammer is about to become royalty -- on the big screen, that is. The 'Social Network' star has been cast to play a prince in an upcoming 'Snow White' film.

According to the Hollywood Reporter, Hammer, who famously played both of the Winklevoss twins in the Facebook biopic, joins Julia Roberts in the film. The actress will trade her sunny disposition for a darker role as an evil queen in the movie.

So far, no Snow White has been cast in the Brett Ratner-produced film, which is set for a June 2012 release by Relativity.

Details surrounding the script remain scarce, but we do know it's a twist on the Brothers Grimm fairy tale in which Snow White teams up with seven dwarfs to take back her kingdom.
