Who she almost played: Despite passing on the role, Rachel McAdams was director Jon Favreau’s first choice to portray Pepper Potts.

Who she could still play: McAdams’s dramatic presence could work magic as a reimagined, younger version of Aunt May.

We know Spider-Man is going to be a teenager in high school, so it could be more realistic for his aunt to be 40 as opposed to 70. It would certainly offer a new take on the property, which is what Marvel is looking to do, and an actress of McAdams’s caliber could easily help sell the transition.
