Marvel's Doctor Strange: Open Your Mind Sneak Peak Released

The world of magic is an intimidating place, especially for someone like Stephen Strange, a believer in science and the practicality of medicine.

That's why it's important to have someone there to help ease the good doctor in, and that will fall to The Ancient One's right-hand man, Karl Mordo, who is being played in the film by Chiwetel Ejiofor. Ejiofor explained his role in the anticipated film in a new behind the scenes featurette.

"Well, he certainly is the intro to Doctor Strange entering this universe. Mordo is very close with the ancient one played by Tilda Swinton. Together both the Ancient One and Mordo sort of begin his training."

While Strange's introduction to the Marvel Cinematic Universe will, of course, be a focal point, the other focus will be on one of the more criticized aspects of most Marvel films, the villains.

"We're excited about villains in this film," said Marvel Studios Head Kevin Feige. "We call them the zealots, these are people who become seduced by what they find on the other side. He (Kaecilius) is interested in spilling the barriers between these dimensions."

You can watch the entire trailer in the clip above. Doctor Strange sets down into theaters on November 4th.
