Marvel

The first trailer for Marvel's Doctor Strange is here, and as promised, it's quite a trip. Benedict Cumberbatch unveiled the movie’s first trailer on Jimmy Kimmel Live! Tuesday night, and by far the most alarming part of teaser is hearing the Brit speak with an American accent.

Directed by Scott Derrickson, Doctor Strange tells the story of Stephen Strange (Cumberbatch), an acclaimed neurosurgeon who uncovers the hidden world of magic and alternate dimensions after a near-fatal car accident. As you can see in the trailer, this film will expose parts of the Marvel Cinematic Universe that have been previously unexplored. (Think Inception for the MCU.)

We're already intrigued by Tilda Swinton, who portrays Strange’s kickass mentor, the Ancient One. "You’re a man looking at the world through a keyhole," she tells Strange in the trailer. "You’ve spent your life trying to widen it. Your work saved the lives of thousands. What if I told you that reality is one of many?"

Notably, we also get a glimpse of Rachel McAdams in the two-minute teaser, and it looks like she's playing a nurse -- a night shift nurse, perhaps? Time, and maybe a bit of sorcery, will indeed tell. Still, we need 100 percent more Chiwetel Ejiofor.

Doctor Strange hits theaters on November 4, 2016.
