Stephen Strange was one of the few heroes in Infinity War that had a decent amount of screentime. It made sense, since Doctor Strange was in possession of the most important Infinity Stone, the time stone. Prior to his appearance in Infinity War, Strange had a small but important cameo in Thor: Ragnarok, and also starred in his own solo film. Doctor Strange made a respectable $677.7 million at the box office, which is just above the first Ant-Man and right below the first Guardians of the Galaxy. 

Marvel Studios head Kevin Feige sat down with CinemaBlend to discuss Ant-Man and The Wasp, but he also touched on the future of the Doctor Strange franchise as well. "Sometimes it's where do those characters pop up? [Doctor] Strange, you know, whenever we do another Strange one, which we will do, it will be a number of years from the first Strange, and yet he's a very big part of [Avengers:] Infinity War," he stated. "So it is just a good problem to have when you have too many beloved characters that people want to see more of, whilst keeping to our core belief that we need to keep exploring nuance and keep doing different types of things." Hopefully, we'll get a sequel soon.
