Benedict Cumberbatch's Doctor Strange will appear in the MCU's Spider-Man 3 as Peter Parker's mentor.

Cumberbatch's casting marks the third major crossover between the films produced by Disney's Marvel Studios and Sony Pictures' "Spider-Man" movies with Holland, after Robert Downey Jr.'s Tony Stark appeared in 2017's "Spider-Man: Homecoming", and Samuel L. Jackson's Nick Fury appeared in 2019's "Spider-Man: Far From Home".

The Hollywood Reporter broke the exciting news this afternoon and confirmed that the Sorcerer Supreme will have a major role in the threequel and will take over as the new "father figure" in Peter's life.

The casting makes sense given that Cumberbatch’s Stephen Strange is based in New York City, as is Holland's Peter Parker, and the characters first shared the screen in 2018's "Avengers: Infinity War" during their battle with Thanos. The third "Spider-Man" movie is set to begin production in Atlanta with director Jon Watts in November. Zendaya, Marisa Tomei, Jacob Batalon and Tony Revolori are all expected to reprise their roles from the previous two "Spider-Man" films.
