Universal Pictures is also in final stages of negotiation with Dominic Cooper to star in the film.
Universal Pictures has revealed it has closed deals with Ben Foster (The Messenger, 3:10 To Yuma, Lone Survivor, Kill Your Darlings, X-Men: The Last Stand), Travis Fimmel (Vikings), Paula Patton (Baggage Claim, 2 Guns, Mission: Impossible - Ghost Protocol, Precious), Toby Kebbell (The Councilor, The East, Wrath of the Titans, War Horse, The Sorcerer's Apprentice, Prince of Persia: The Sands of Time, and Rob Kazinsky (True Blood, EastEnders, Pacific Rim) to appear in the upcoming Warcraft movie adaption.
Dominic Cooper (Captain America, Mamma Mia) is currently in negotiations with the studio for a starring role.
Other actors who were previously rumored for the film but not confirmed in the official press release: Colin Farrell, Paul Dano, Anton Yelchin and Anson Mount. Back in September, we heard that Farrell was reportedly negotiating for a starring role, and was "50/50" on whether he will accept it or not. I guess he did not.
Production of the movie, which was penned by Charles Leavitt and rewritten by Duncan Jones, is set to begin in January 2014, aiming for a December 2015 release date.
Someone with more knowledge of movies and TV shows will have to fill me in on these actors, as I can't vouch for their ability off the top of my head. Rob Kazinsky was pretty good in Pacific Rim I guess.
