Avengers 4 doesn't come out until next May, but filming is already done since it was shot back to back with Avengers: Infinity War. It's not often that Marvel movies get such a long time to do the edit, and Kevin Feige spoke to Birth.Movies.Death. about the process.
We're just starting the edit. The brothers have worked on their cut, and we've been together in the editing room for a couple weeks now, so it's very early days. But it's much earlier than usual, right? Usually we're still filming. Captain Marvel comes out in March, while this one comes out in May and we're already starting. It's fun to get a jump, it's good having already shot the majority of the movie. So we're just getting into our traditional editorial process now.
When asked if the extra time was going to give them time to try something different, Feige said that they would fill the time regardless of how much of it there was.
Theoretically. We try – what's the analogy, that a goldfish will grow to the size of the bowl? Ant-Man and the Wasp had very little post and yet we made a lot of strides in post, and we did a lot of very good maneuvering on it with the limited time we had. Avengers 4 has much more time; Ragnarok had much more time and we did a lot. You always fill the time you have. Either you have a lot of time and it really motivates you to think things through, or you have no time, and it really motivates you to think things through!
We don't even have a title for Avengers 4, though rumors are suggesting we might find out later this year. Sources say that the title is a spoiler of some kind, so we'll have to see.
