Benedict Cumberbatch is set to reprise his role as Doctor Strange in Avengers: Infinity War, but he's not sure when, or if, he'll have his own solo outing again.

When speaking with Entertainment Weekly in an interview regarding the upcoming Avengers flick, he was asked if he had any idea as to when he'd be shooting Doctor Strange 2 - which hasn't officially been confirmed or announced by Marvel Studios.

"Not at the moment, no. The masterplan is continually in flux, so it would be out of order for me to speculate," the actor revealed. The movie did practically set up the villain of a would-be sequel, with Chiwetel Ejiofor's Mordo taking a villainous turn in a post-credits scene.

Marvel Studios has purposefully kept its slate beyond Avengers 4 very secret, as it may just reveal some of the results of the upcoming ensemble piece. This, in theory, is why a Doctor Strange sequel has never outwardly been confirmed. It'd be hard for the studio to pass the opportunity to bring Cumberbatch, Benedict Wong, and Rachel McAdams back though, with the first movie making $677 million in the worldwide box office.

Not only that, every character that has had a solo outing has returned for a couple more times -- rounding out a trilogy of movies focussing on their own adventures (bar The Hulk, though he had a main role in Thor: Ragnarok, and there's a whole situation regarding rights that would make a sequel tricky to pull off). Even Ant-Man has its own sequel on the way, so it's only right that Cumberbatch gets the chance to continue as the Sorcerer Supreme beyond Avengers team-up films.

The director of Doctor Strange, Scott Derrickson, has been rather vocal regarding his hopes for a sequel, and which direction he'd take it. He previously revealed that he wants to use the Dark Knight trilogy as inspiration, creating more compelling villains; Mads Mikkelsen's Kaecilius was hailed as forgettable by many fans.

Doctor Strange's new-found abilities open up many doors -- and dimensions -- for a sequel, which is something Derrickson wouldn't shy away from should he return to helm the movie. “The alternate dimensions and possibilities of the multiverse that we set up with the first film already give limitless possibilities,” Derrickson said last year. “What I will say is that the goal would not be to under-utilize that, or to create something that was less innovative than the first ‘Doctor Strange.’ The comics, especially the [Stan] Lee/[Steve] Ditko comics, were always pushing into unexpectedly weird places and storylines.”
