"He came up in a time protecting an area, and the way he protected this area was through magic," Foster said. "As peace returned to this land he took a break. He hung up his staff, so to speak, or let his guns get dusty. We meet him as his friends are returning asking for his help in a battle." We won't spoil how closely that does - or doesn't - fit with the established Warcraft lore, but you can always read up on the character if you like.
Warcraft has already finished filming, but will require extensive post-production work due to the movie's use of CG characters. Foster himself seemed impressed with the work done so far. "The way that they're pushing motion-capture - I just saw some of the test footage - it's unlike anything I've ever seen," he said. "It's performance-capture. It pushes it to the next level. It's going to be one hell of a 3D event."
