Announced in January of this year, when it was said that the actor was "in talks" to join the film’s cast, Chiwetel Ejiofor is apparently no on-board, as the character he’s signed up to play has been revealed.

Per Deadline, he will play Baron Mordo, Doctor Strange’s archenemy, whose full name is Baron Karl Mordo. Per the Marvel wiki, Mordo began his tutelage under the Ancient One as early as the 1930’s, already an adult, and residing in the Ancient One’s lair brought him reduced aging. The Ancient One realized that Mordo’s lust for power made him dangerous but chose to teach him anyway, feeling that he could at least keep a watchful eye on him. Mordo was immediately resentful of Doctor Strange when he began studying under the Ancient One and magically restrained him from speaking when Strange accidentally walked in on Mordo’s plot. The plot failed, Strange became the Ancient One’s disciple, and Mordo eventually left. Mordo continued his studies and became a fierce rival of Doctor Strange. They battled many times. 

In the comics, Baron Mordo is a Transylvanian during the era of the Austro-Hungarian Empire.

I’ll defer to Doctor Strange experts to chime in with further thoughts on today’s news.

Benedict Cumberbatch stars in Marvel’s upcoming "Doctor Strange" big screen adaptation. And Tilda Swinton will play The Ancient One. 

Talk about one hell of a strong cast here!

Disney has set the film for release on November 4, 2016.
