During New Orleans WizardWorld, "Captain America: The Winter Solider" co-director Joe Russo teased the character lineup of "Avengers: Infinity War" and explained how he and his brother Anthony planned to approach the films.

When asked by ComicBook.com if the Guardians of the Galaxy would appear in "Infinity War," Russo responded, "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."

"We're just going to approach the cosmic side with the same fervor that we did the earthbound work we've been doing," he continued. "We also are going to work really hard to bring a psychological realism. We obviously can't bring a naturalism to it because it doesn't really exist outside of science fiction, but we can bring that psychological realism to it, to the characters, and that's going to be our focus.

Directed by Joe and Anthony Russo, "Avengers: Infinity War - Part 1" is scheduled for release on May 4, 2018.
