Pinewood Studios outside of London, England has become a favorite filming spot for Disney and Marvel Studios. While Disney currently has Star Wars: Episode VII filming there, they’ve made it a home base for many Marvel projects, as Avengers: Age of Ultron, Guardians of the Galaxy, Thor: The Dark World, and Captain America: The First Avenger all filmed primarily at the studios.
Add Doctor Strange to that list, according to a report by THR. They noted there aren’t official announcements from Pinewood or Marvel/Disney yet, however. The report also says that Doctor Strange is assumed to be the July 2016 Marvel Studios movie, following about two months after Captain America 3. No star has been cast yet for the film, though Joaquin Phoenix has been at varying degrees of talks, depending on which rumor you read on which day. Scott Derrickson, however, is confirmed as the director of the film, perhaps a hint on a darker, more horror-filled direction for the Sorcerer Supreme.
