In an interview with Yahoo! Movies (via SlashFilm ), Markus and McFeely said they've written several drafts, as they're currently on the third draft of Avengers: Infinity War and working on the second draft of the untitled followup They're working on both films as much as possible, noting that "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." The pair also said that things are constantly changing, as "notes are coming in and all sorts of production stuff is coming in" that requires them to make adjustments.Markus also discussed how they're keeping track of the massive cast of the ever-expanding MCU and handling any character deaths. He said they lock themselves in a room with directors Anthony and Joe Russo (along with a few Marvel execs), where "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" and used that as a guide before they "began to shuffle the cards around."In fact, Markus said they even have a card for Darcy's boyfriend from Thor: The Dark World, before jokingly adding that there's a big scene in the film "when Darcy’s boyfriend and Galactus get together."Marvel's The Avengers: Infinity War will open in theaters on May 4, 2018, while the currently untitled followup is set to debut on May 3, 2019. Thanos actor Josh Brolin recently teased what fan can expect from the movie, saying he was "blown away" by the story, which pits Thanos against everyone else
