In the above video, Feige is asked about Miles Morales with Feige responding:
We've always thought it should be Peter. We've never seen the MCU version of Peter Parker. It felt like we needed to see that first. Miles, I think is awesome. There are opportunities for him, for sure, if this all works and continues.
The potenital for a non-white Spider-Man is then brought up, with Feige responding:
Maybe. The field is very wide right now in terms of who we are looking at within a certain age range.
Feige also answered questions on Captain Marvel and offered they didn't want to introduce her flying around without anyone knowing her character, and Feige offered in an earlier version of an Avengers 2 script, Carol Danvers was a part of it.
Regarding Doctor Strange, Feige offers the supernatural side of the MCU is something they have been talking about for a long time. Feige says director Scott Derrickson and the producing team are scouting locations in NYC with filming to take place in London this November. Feige also offers Benedict Cumberbatch is so excited, and they haven't discussed Strange's accent yet (Cumberbatch is British).
Feige is also asked if there is a possibilty to add in other Marvel movies in Phase 3, like a Hulk movie or Iron Man 4. Feige said they already added in Spider-Man, but said he would be more worried about having to change the schedule again than adding in more movies.
Regarding the two part Avengers: Infinity War films, Feige says they wouldn't be one big movie cut in half, but two distinct movies.
Captain America 3 shoots in two weeks, with Feige offering Cap is still the primary focus.
