Avengers: Infinity War has a massive hurdle ahead of it; not only is it Marvel Studios' first two-parter, but it also has the immense task of culminating every film that came before it, along with including a very long list of characters. In an interview with Cinemablend, the film's writers, Christopher Markus and Stephen McFeely, say they have currently completed the film's second draft, but have admitted that they won’t really be entirely sure how everything will work until all of the other movies in Phase Three are finalized. "Some of it is informed guesswork," said McFeely on just how close to 'finished' the duo can get at this point. "Some of it is constantly pestering people who are making those [other] movies to tell us what they’re doing. And sometimes it is us going, ‘It would be massively beneficial if this person could be in this place at the end of your movie. I don’t care what he does in your movie, but by the end of it…’"
Markus continued, "And you know, we write it, we assume when we write it and rewrite it and rewrite it, as more information comes in, we will be adjusting. When we’re turning in the first draft, it’s absolutely that, a first draft, and we’ll go through a lot before we get to November.".
Along with all our heroes, the writers also have to introduce main villain Thanos, who we've only received a few glimpses of so far. With the numerous characters already included, it's a massive task to give the Mad Titan his due, but the writers promise that there will be plenty of time devoted to the formidable villain. "I think the problem will be solved simply because he will be the villain, have lots of scenes, and you’ll understand his point of view," said McFeely. "He’ll do lots of dastardly things. I’m not saying he’s not a challenge. He is, because he’s got so much power, but I guess find the, I’m using this in quotes, ‘the human underneath,’ but we’ll have the opportunity because he’ll have a lot of scenes." Markus elaborated on the importance of giving the character depth, "Yeah, and like any character, we’re going to learn about the character, not just as a villain. If you’ve got the guy taking you through more or less two movies, he can’t just be twisting his mustache the whole time."
Part 1 of Infinity War (which will soon have a new title) is set to release May 4, 2018.
