In a few years, the Marvel Cinematic Universe as we know it will come to an end. Even as the universe moves forward past Phase 3, the movies have currently been building up to an eventual mega showdown against the Mad Titan himself, Thanos. So far we’ve seen little from him besides sitting, plotting, and putting on empty gloves, but that will all change when Avengers: Infinity War rolls around.

We recently learned that Disney and Marvel Studios have dropped the Part 1 from the tile for the third Avengers movie, making it simply Avengers: Infinity War, but they left what used to be Part 2 more vague, labeling it as Untitled Avengers. With the very much connected films set to start filming later this year, it is unclear when exactly we will get the title for the fourth Avengers film, but I’m kind of hoping they hold off for a while to maintain some mystery. That said, even though no title has been announced, Marvel likely has a title chosen as they continue to work in the pre-production stages, and that means Christopher Markus and Stephen McFeely are tirelessly working on the script. When they were asked by Yahoo! Movies about the current state of the script, the noted that they are in different stages with each film.

We’re many drafts in. We’re on the third draft of movie one and the second draft of movie two. [We’re writing them in tandem] as much as we can. On any given day, you’re only working on one but that doesn’t mean that next week, you aren’t working on the other one. And certainly, notes are coming in and all sorts of production stuff is coming in, like for instance, ‘that thing over there is now a window not a door so adjust that.’ Or, ‘we’re not going to this town now, we’re going to this town.’ That kind of stuff happens constantly and will continue to happen for the next few months.

This has to be the most rigorous script they have written to date, with so many moving parts and characters that they are responsible for weaving together into one intricate storyline over the span of two movies. They knew this would be the case before accepting the job, but with so many characters at their disposal it could be hard to keep track of it all. Previous reports pointed to 67 characters that they could use, and while they would not go into a specific number, they did show just how diligent they were being with their work.

When we lock ourselves in a room with the Russo brothers and a couple of execs from Marvel, one wall has cards for movie one and the other wall has cards for movie two and another wall has little baseball cards of every character still alive in the Marvel universe – down to Darcy’s boyfriend in Thor 2 – literally, anybody who did not die and has been established as alive. And then we looked at that began to shuffle the cards around. So basically, the big scene is when Darcy’s boyfriend and Galactus get together and….[laughs].

The most noticeable thing from this quote is obviously the name drop of Galactus. However, I do not think this is an indication that Marvel has got the rights back for this character because I can’t imagine them letting that type of thing slip in an interview. If you watch the full interview at the link below, they make a joke earlier about Galactus appearing as some type of spoiler, and with them then referencing him and Darcy’s boyfriend having a scene together, it is pretty obvious that this likely is not the case. But still, Galactus showing up would certainly complicate things for all parties involved.

Avengers: Infinity War is scheduled to hit theaters May 4, 2018. Untitled Avengers is scheduled to hit theaters May 3, 2019.
