Marvel fans are more excited than ever for Doctor Strange 2 after Spider-Man: No Homecoming ripped through the multiverse. Now anything is possible in the Marvel Cinematic Universe. And as Benedict Cumberbatch teased, the Doctor Strange sequel will surprise a lot of people in the credits.

Benedict Cumberbatch teases his character's journey in 'Doctor Strange 2'

During an interview with Empire for their latest issue, Benedict Cumberbatch previewed what awaits Doctor Strange in Doctor Strange 2 .

"There's a lot of accountability," the actor revealed. “And a lot of self-discovery. Strange is almost a stranger to himself before this movie unfolds and reveals what, essentially, is in his nature, which he must then face or resist or fall or become.

Cumberbatch added: “There are some very bold ideas and extraordinary tests of Strange and encounters. There are some very unexpected conclusions.

As the magazine pointed out, Strange will uncover answers about who he is, and those will be hard pills for the Wizard to swallow. And everything Doctor Strange, played by Benedict Cumberbatch, discovers in the sequel will surprise him and audiences alike.

'Doctor Strange 2' could have the same level of success as 'Spider-Man: No Way Home', according to Benedict Cumberbatch

Doctor Strange 2 is bound to be an important movie, given its subject matter. Marvel superheroes, including Strange, Scarlet Witch and newcomer America Chavez, will jump from universe to universe in the film. And that means they will meet many exciting characters.

"It's a big, big movie," Benedict Cumberbatch told Empire. "It's going to be an absolute riot. And if he succeeds with the level of ambition he has, we will have Spidey-level success. Here, I'm going to plant my flag in the sand.

Of course, the actor is talking about Spider-Man: No Homecoming , which starred Doctor Strange. The third Spider-Man movie grossed over $1.8 billion at the box office, making it the highest-grossing film of 2021 and the sixth-highest-grossing film of all time. It'll be quite a feat if Doctor Strange 2 is as successful as Spider-Man: No Homecoming, but Benedict Cumberbatch thinks it will.

All the rumored and teased cameos in the 'Doctor Strange' sequel

As seen in the trailer, Benedict Cumberbatch will play many variations of Doctor Strange in Doctor Strange 2 . Variants include Supreme Strange, Zombie Strange, and Defender Strange. Fans also got a glimpse of Zombie Scarlet Witch, played by Elizabeth Olsen, in the trailer.

Patrick Stewart can also be heard off-screen in the preview. He's likely reprising his role as Professor X, but he could be playing a variation of the mutant.

As for the rumored cameos, many fans believe that Superior Iron Man, played by Tom Cruise, will appear in the movie. Reed Richards and Deadpool are a few other names that pop up often regarding cameos in the Doctor Strange sequel. However, Marvel has yet to confirm any of these rumors.

Doctor Strange in the Multiverse of Madness premieres exclusively in theaters on May 6.
