The first trailer for Marvel's "Doctor Strange" debuted on "Jimmy Kimmel Live!" on Tuesday.
The film stars Benedict Cumberbatch as Dr. Stephen Strange alongside Tilda Swinton as the Ancient One and Chiwetel Ejiofor as Baron Mordo. Strange is a brilliant but egotistical surgeon who travels the world to restore his skills after a car accident leaves him unable to operate.
In his travels, he meets the Ancient One, who teaches Strange the ways of magic in order to protect the Earth from a host of mystical foes.
In the chilling teaser, Strange is told to "forget everything that you think you know."
"You are a man looking at the world through a keyhole, you have spent your life trying to widen it," a female voiceover continues. "Your work saved the lives of thousands. What if I told you, that reality is one of many."
"I don't believe in fairytales about chakras or energy or the powers of belief," the doctor says.
"You wonder what I see in your future? Possibility," Swinton's mystical bald-headed figure later tells him, as she teaches Strange about the mystical arts.
