Captain America 2: 20 Easter Eggs, References & In-Jokes You Need To See
4. Doctor Strange
In the sequence when Captain America is told of the real agenda of Project Insight by treacherous SHIELD leader Jasper Sitwell (Maximiliano Hernandez,) he identifies a number of targets who would be taken out as part of the helicarriers' genocide of future terrorist targets (based on Zola's magic algorithm that somehow predicts the future from your web history.) The target that stands out the most is Steve Strange, a mention that all but confirms the future inclusion of Doctor Strange in the Marvel world. And Kevin Feige has already stated how he would handle the inclusion of magic in the Avengers' world:
"Are you watching the Cosmos series? That's magic, . It's unbelievable. If somebody knew how to tap into that stuff, what's the difference between that and magic? You don't get into it in Harry Potter, but if a scientist went to Hogwarts he'd find out how some of that stuff is happening! We're not going to spend a lot of time on that, but there will be some of that. And particularly for a character like Strange, who goes from a man of science to a man of faith and who traverses both worlds. And sometimes there won't be an answer! Sometimes he'll want an answer - "How is this happening?!" - and nothing."
