Doctor Strange: 7 Tony Stark Cameos That Would Rule

7. Spider-Man: Homecoming Setup

If Tony Stark is to appear in Doctor Strange, then this seems like one of the easiest ways to pull it off. Ok, it wouldn't technically be in Doctor Strange, as there wouldn't necessarily have to be any interaction with the Sorcerer Supreme, but rather a standalone post-credits scene.

Since Spider-Man: Homecoming is a film we know Robert Downey Jr. will be in, and that's coming a couple of films after Doctor Strange (with Guardians of the Galaxy in between), then it's a timely fit for Marvel to start promoting it here, especially since they'll no doubt want to make the most of the fact that they have Spidey back in the MCU.

It could well be a scene taken from the movie, much like the Bucky scene at the end of Ant-Man, or they could find some way of fitting Strange into it: with Stark and Tom Holland's Peter Parker together, watching a news broadcast about Stephen Strange and/or having a conversation about him, and Stark talking of wanting to bring him in to the Avengers, probably with one (if not the pair of them) delivering some solid quips about him too.
