With just 36 days and counting left until Infinity War hits theaters, new details are still surfacing from set visit coverage that starting rolling out last week. One of the many questions fans have about this Phase 3 superhero adventure is how much time is spent on Earth, and how much is spent in the cosmos, a fair query since practically every MCU character is said to be present in this movie. Writers Christopher Markus and Stephen McFeely were asked this very question on set, with McFeely hinting that there is a rather even split between Earth and the cosmos.

"We can't give you a percentage but it's fairly split. That's part of the nature of all these groups coming together."

This naturally adds to the epic scope of the film, with characters like the Guardians of the Galaxy meeting others from other realms such as Thor (Chris Hemsworth) and Loki (Tom Hiddleston), who were last seen in the post-credits scene of Thor: Ragnarok as their ship was approached by another, confirmed later by Kevin Feige to be Thanos' ship known as Sanctuary II. The first trailer for Avengers: Infinity War also featured Thor meeting the Guardians for the first time, so it's possible that they help Thor escape from Thanos' clutches, but that has yet to be confirmed. The writers did reveal that they wanted to set the stage for something so massive that not only the Avengers, but everyone in the MCU simply had to come together to face Thanos. Here's what Christopher Markus had to say about the stakes in the movie, which spans the entire globe, not just America.

"We wanted to give it, not have it be the feeling that it all comes down to Earth every time. It's this sort of 'Earth-ist' point-of-view that you have to tell. We needed a broad canvas the whole time, so that it didn't feel like, coincidentally, every stone is on, is in America."

Earlier this week, we showed you Empire Magazine covers that featured a number of MCU characters together, while the Avengers: Infinity War trailer teased some unusual pairings, like the introduction of Spider-Man (Tom Holland) and Doctor Strange (Benedict Cumberbatch). Christopher Markus revealed that while the tone of the movie is quite serious, with massive stakes, these unusual team-ups will help bring some levity to the story. Here's what Markus had to say about how they approached the humor in this movie.

"Sometimes you play into it. You cut to the Guardians and it's a breather. If you're going from T'Challa and Captain America being very intense, you cut to Quill and Drax and it's like, sigh. It doesn't mean they're not carrying as much plot, it just means the tone is different."

The writers previously wrote all three of the Captain America movies, 2011's Captain America: The First Avenger, 2014's Captain America: The Winter Soldier and 2016's Captain America: Civil War. They also wrote Avengers 4, which closes out Marvel Phase 3 when it hits theaters on May 3, 2019. The writers made these revelations during an on-set interview with ComicBook.com.
