The Marvel Cinematic Universe is about to get a whole lot stranger, thanks to Benedict Cumberbatch.

No, we don't expect the "Imitation Game" star to start photobombing Iron Man, Captain America, or any of Earth's other mightiest heroes. Instead, he'll be right up front in the photo itself, as the star of "Doctor Strange," director Scott Derrickson's movie about Marvel's most magical hero.

Cumberbatch's "Strange" isn't due out until late next year, so the actor has plenty of time before he starts diving deep into the role. As such, some of Cumberbatch's future Marvel stars don't know him that well quite yet — like Mark Ruffalo, the Hulk actor at the center of the "Avengers" franchise.

"I don't know him very well yet," he admitted on the Golden Globes red carpet, "but he's really good. He's not doing so bad."

Whether or not Ruffalo knows Cumberbatch now, they're bound to get to know each other much better in the years ahead, what with the two-part "Avengers: Infinity War" hitting theaters in 2018 and 2019. Marvel fans expect just about every hero, from Hulk and Strange to the Guardians of the Galaxy and beyond, to appear in the "Avengers" mega-movie — so even now, Ruffalo certainly has his eye on someone who just might be a future collaborator.

"It's great," Ruffalo said of Cumberbatch's casting. "It's amazing. It's a good combination."

"Doctor Strange" hits theaters on November 4, 2016.
