Benedict Cumberbatch made an appearance on Jimmy Kimmel Live! on Tuesday to debut the first teaser trailer for his upcoming venture into the Marvel Cinematic Universe, Doctor Strange.

The teaser introduces Cumberbatch’s character, Dr. Stephen Strange, a surgeon who suffers a horrific car accident, then discovers a world of mysticism and alternate dimensions.

“You’re a man looking at the world through a keyhole. You’ve spent your life trying to widen it,” the Ancient One (Tilda Swinton) tells Strange. “Your work saved the lives of thousands. What if I told you that reality is one of many?”

At first, Strange seems skeptical. “I don’t believe in fairy tales about chakras, or energy, or the power of belief,” he says, in a gruff American accent.

But the Ancient One is undeterred. “You wonder what I see in your future?” she asks. “Possibility. There are other ways to save lives.”

The teaser also features some visually-impressive, Inception-style world-bending, as well as a first look at several other central Doctor Strange characters, including Chiwetel Ejiofor’s Karl Mordo and Rachel McAdams as a fellow surgeon who connects Strange back to his old life.

While Cumberbatch’s character is seen only in street clothes throughout the trailer, the final shot teases his full Doctor Strange regalia, as the character ascends the steps of the Sanctum Sanctorum. The Sanctum’s signature swirling window is also featured in the film’s first poster, which was tweeted by director Scott Derrickson on Tuesday.

Marvel also tweeted another mind-bending poster for the film after the debut of the trailer:
