Tilda Swinton is in talks to co-star with Benedict Cumberbatch in Marvel’s “Doctor Strange.”

Scott Derrickson is directing the comicbook movie.

Cumberbatch will play Stephen Vincent Strange, a former neurosurgeon who becomes the next Sorcerer Supreme and primary protector of Earth against magical and mystical threats. Marvel Comics vets Stan Lee and Steve Ditko co-created the character in 1963. Strange’s mentor is a Tibetan mystic known as the Ancient One, who is training pupils to be the next Sorcerer Supreme. In the comics, the character has been a male, and Marvel Studios was initially searching for a male actor. Given Swinton’s interest in the film, however, the studio has now rethought the role.

“Doctor Strange” will debut on Nov. 4, 2016.

Swinton will be seen with Amy Schumer in Judd Apatow’s upcoming comedy “Trainwreck.” She is repped by UTA and Hamilton Hodell in the U.K.

The news was first reported by the Hollywood Reporter.
