Casting is underway for Duncan Jones' World of Warcraft movie. According to Deadline, Colin Farrell and Paula Patton are in negotiations for leading roles. Production begins in January.
Being slightly obtuse and basing it on looks alone, I could see Young Medivh and Garona Halforcen in those two. I don't particularly want to, but I kinda see it.
I still think that rumour of it being based around Medivh and the Dark Portal is too weird an angle for this movie though. We'll see.
