Legendary Pictures CEO, Thomas Tull, admitted to the challenges of bringing Warcraft to the big screen. Speaking to Slashfilm, Tull explained the current difficulties.
“A lot of times, what has happened in the past is, studios have said, ‘How many people play that game? OK, then that means they’ll probably all go out and buy tickets.’ That is an incredibly poor way to make a movie.”
Tull admitted that Legendary Pictures has a lack of experience when it comes to adapting game franchises for the big screen, saying, "So for us, it’s that we don’t know how to make a movie out of Warcraft, the video game. It’s the incredible story, the war, and these races, and everything these guys at Blizzard have come up with. They have 100 books, and just this incredibly rich world that they've created."
So instead of trying to capture the complete storyline of the game itself, Tull hinted that it'll probably take place within the same universe, but not necessarliy the complete arc.
Blizzard's Warcraft franchise has been in the pipe for a film adaptation since an announcement at the Electronic Entertainment Expo (E3) way back in 2006. The film is expected to beginning shooting early next year with director Duncan Jones (Moon, Source Code) following the departure of Sam Raimi. At a reported budgets of around 100 million gold and lumber.
