Will they? Won’t they? Neither “Guardians of the Galaxy” director James Gunn, nor the “Avengers: Infinity War” directors Joe & Anthony Russo have made a statement about “Guardians of the Galaxy” joining the fight in “Avengers: Infinity War”.

While speaking to comicbook.com, Joe Russo said, “That is another one that we would have to reserve as a surprise. But we will say this. People will not be disappointed in the amount of characters in the movie. The concept of Infinity War is that the Marvel universe unites to battle the greatest threat to the world and universe that you’ve ever seen, and we’re going to honor that concept.”

The movie sees Thanos trying to collect all of the Infinity gems for his Infinity gauntlet.  According to International business times it is unclear how much of the Marvel Cinematic Universe will be united.

Even fans have been curious for some time about the introduction of these cosmic crime fighters to the rest of the Marvel Cinematic Universe. While nothing is finalized right now, it is just speculation that they will either be a part of the first part of “Avengers: Infinity War”.

Anthony Russo didn’t exactly sound hopeful at an interview with Super Interessante at Comic Con Experience Brazil. Nerdist quotes him as saying, “It’s complicated. When we start to serialize the telling of stories, it’s difficult. You have to have a lot of control and focus on the course of history.”

“The films are controlled by a group led by Kevin Feige, so they function as a unit. Other products, even if they are from Marvel, are controlled by others. Then there is the possibility of a crossover, but it’s more complicated.”
According to movieweb, Joe Russo doesn’t want to come right out and say which characters are in the movie. Instead, he suggests that it will likely include all of them. He was, however, more open about the cosmic nature of Avengers: Infinity War.

Avengers: Infinity War Part 1 is scheduled to be released in movie theaters on May 4, 2018, while the second part will be released in May 2019.
