Doctor Strange: Marvel unveils sneak peek behind the scenes

The Marvel Cinematic Universe is about to get bigger (and a lot more magical) with the upcoming Doctor Strange movie. Now Marvel has offered a revealing glimpse behind the scenes of the supernatural superhero flick.

Collider reports the clip (above) is a snippet from the extended Doctor Strange sneak peek that will be included on the Captain America: Civil War Blu-ray. In it, co-stars Tilda Swinton (the Ancient One), Mads Mikkelsen (Kaecilius), and Chiwetel Ejifor (Karl Mordo) open up about their roles in the movie starring Benedict Cumberbatch in the title role.

For those who haven't read the comics, Doctor Strange is an expert surgeon who suffers nerve damage that robs him of his purpose in life until a mystical being known as the Ancient One teaches him to become the newly designated Sorceror Supreme.

The new video also features a lot of concept art from the movie, and it shows just how truly strange the MCU is about to become. Doctor Strange is set to premiere Nov. 4, but we're already gearing up. Check out hidden details you missed in the trailer, and a closer look at Mikkelsen's villain.
