Doctor Strange's presence in the Marvel Cinematic Universe undoubtedly won't stop at his upcoming solo movie. Though he hasn't explicitly confirmed anything, Benedict Cumberbatch has made it pretty clear where he'll appear next - Avengers: Infinity War.
Cumberbatch recently spoke to Empire (viaExpress)about the “logistical challenge of aligning his schedule with those of Robert Downey Jr, Chris Hemsworth, Elizabeth Olsen and Paul Bettany."
“To get us all together will be quite something. That’s why this character is being introduced, to open up the next chapter. So watch this space to see how that unfolds.”
While he doesn't outright state that Strange will appear in Infinity War, the implication is clear. But Marvel may need to use the Time Gem to piece all those busy schedules together - director Scott Derrickson recently revealed that Cumberbatch almost missed the role of Strange due to his busy schedule.
Doctor Strange hits theaters November 4, while Avengers: Infinity War is scheduled for a May 4, 2018 theatrical release.
