Later this year, production will begin on Marvel's epic two-part adventure Avengers: Infinity War, which is set for release in May of 2018 and 2019. The studio hasn't offered any confirmation about which cast members will be present in this superhero adventure, but directors Anthony and Joe Russo have previously teased that there will be upwards of 67 Marvel characters in the movie. Though many of these characters won't have leading roles. Still, many are wondering exactly who will be showing up for Infinity War, and who won't. Today, it seems we have gotten confirmation about a popular superhero group's inclusion from writers Christopher Markus and Stephen McFeely.

The two-part Infinity War movie has been said to be the "culmination" of the entire Marvel Cinematic Universe thus far, and while the MCU certainly won't "end" after this movie, it will close out Phase 3, and likely pave the way for big changes in Phase 4. No plot details are confirmed, and it's assumed that the current and past Avengers will all show up to fight Thanos. But many have wondered whether or not the Guardians of the Galaxy will put in an appearance to help out in the ensuing battle. During an interview with Nerdist, Christopher Markus had this to say, when asked if the Guardians are putting in an appearance, mostly confirming that they will.

"Let me put it this way. You know who owns that gauntlet, right. And you know who's in another movie and his kids are in that movie... you do the math."

The owner of the Infinity Gauntlet is the Mad Titan himself, Thanos (Josh Brolin), who was featured in the original Guardians of the Galaxy, along with his daughters Gamora (Zoe Saldana) and Nebula (Karen Gillan). The site points out that one of the Guardians, Drax the Destroyer (Dave Bautista) plays an important role in the Infinity War comic book storyline, which is another big indication that the Guardians will come to Earth and join the war against Thanos. However, we don't know if the Guardians will be featured in Infinity War Part I or Infinity War Part II, or if they'll appear in both movies.

The writers revealed in another interview last week that they recently finished their second draft of the script for the two-part movie, although the writers added they aren't sure how many drafts they will write before production starts in November. They also said that it's essentially "impossible" to have a finished script now, since they are consulting with the filmmakers on the other Marvel movies to make sure everything falls in line with the studio's plan. Hopefully we'll get the first plot details for Avengers: Infinity War before production begins later this year.

Phase 3 will continue with Doctor Strange (November 4), followed by Guardians of the Galaxy Vol. 2 (May 5, 2017), Spider-Man: Homecoming (July 7, 2017), Thor Ragnarok (November 3, 2017) and Black Panther (February 16, 2018), before Avengers: Infinity War Part I arrives in May. Marvel will then release Ant-Man and the Wasp (July 6, 2018) and Captain Marvel (March 8, 2019) before Avengers: Infinity War Part II arrives in May 2019. Take a look at the video below, which includes an excerpt of Nerdist's video interview with Avengers: Infinity War writers Christopher Markus and Stephen McFeely.
