Chiwetel Ejiofor is well known for his role in the award winning drama 12 Years A Slave.
He will star alongside Benedict Cumberbatch in the Scott Derrickson-directed feature. We can also expect to see The Ancient One, who is different from what was in the comics, as the films versions swaps genders for a female character.
Doctor Strange and Mordo gained the knowledge in the mystic craft under the tutilage of The Ancient One, but Mordo was the only one brazen enough to try and kill his master. Some real Shaolin badassery right there.
In the comic, Doctor Strange is a brilliant but arrogant surgeon who comes to realise after a life-altering car accident that his power is beyond the material world.
