Marvel is finally ready to conjure up a sequel to Doctor Strange.

Scott Derrickson, who directed and co-wrote the mystical Marvel hero's initial 2016 outing, has quietly finalized a deal to direct the new installment.

A search for a writer to pen the script is about to get underway.

Benedict Cumberbatch will return as Stephen Strange, the good doctor-turned-master of the mystic arts, as will Benedict Wong, who plays his right-hand man, Wong. Rachael McAdams, who played Stephen Strange’s love interest, is likely to return as well.

Strange was last seen de-materializing in the $2 billion-grossing Avenger: Infinity War, where one of his lines of dialogue served as the inspiration for the title of the fourth Avengers movies, Avengers: Endgame.

Marvel has been tightlipped about its plans for life after Endgame, which it is calling Phase Four. After all, how much can there be when half your heroes are supposed to be dead?

In any case, sources tell The Hollywood Reporter that the plan is for the script to be hashed out in 2019 with an eye toward a spring 2020 production start. If all goes well, the movie would be casting its spell on audiences in May 2021.

Marvel had no comment.

Derrickson carved out a resume of horror movies such as The Exorcism of Emily Rose and Sinister before making 2016’s Strange, which grossed $677.7 million worldwide. Earlier in 2018, he directed the pilot for TNT’s TV adaptation of Snowpiercer, but parted ways with the production after the showrunner was replaced.

He is repped by WME, Brillstein Entertainment Partners and Ziffren Brittenham.
