Doctor Strange Trailer Breakdown: 25 Things You Need To See

14. Chiwetel Ejiofor

Given the fact that we know Chiwetel Ejiofor is playing Baron Mordo - one of Strange's longest running villains and a former fellow pupil of The Ancient One - it makes sense that this is going to be his origin story too.

It's likely that he is initially aligned with Strange against Mads Mikkelsen's mysterious villain, but his desire to kill The Ancient One to become the supremely powerful sorceror will drive a wedge between them and they'll end up clashing more directly in the sequel after Mordo is cast out.

Hopefully, we'll also then get to see Dormammu alongside him too.
