Doctor Strange: Action-packed featurette unveils magical origin story

Doctor Strange will bring a spectacular kind of magic to the Marvel Cinematic Universe, and a new video shows us exactly where it comes from.

An official U.K. featurette (via Collider) explains the superhero's backstory with a ton of eye-popping footage from the upcoming flick. It also includes interviews with cast members Benedict Cumberbatch, Tilda Swinton, Chiwetel Ejiofor, and Rachel McAdams, along with thoughts from producer and Marvel Studios president Kevin Feige. Check it out above.

The film has already generated a fair amount of controversy. Director Scott Derrickson took a lot of heat when he cast Swinton in the role of the Ancient One, a character consistently depicted in the comics as an Asian man. In response, Derrickson recently told the Los Angeles Daily News that he decided to bring back a character that was originally cut from the script: the doctor's Asian butler (played by The Martian's Benedict Wong).

Doctor Strange arrives in theaters Nov. 4, and Marvel recently unveiled the trippy international poster.
