When the Guardians join the Avengers in 2019's "Avengers: Infinity War," don't expect them to overtake the Avengers as the stars of the film.

In a recent interview with Nerdist, Star-Lord actor Chris Pratt talked about the differences between "Guardians of the Galaxy Vol. 2" and "Avengers: Infinity War," the latter of which will see our favorite galactic heroes join Earth's Mightiest Heroes for the first time on the big screen. The actor reaffirmed that, while "Vol. 2" is very much a Guardians film, "Infinity War" is still very much an Avengers film -- even though the Guardians will have a strong presence in it.

“We definitely will have a strong presence, but we are playing supporting cast - you know what I mean? We’re there to help them tell an awesome Infinity War story. But Guardians is cosmic. It is its own special off-shoot of the Marvel Cinematic Universe.”

Pratt's comments aren't entirely surprising, of course. The cosmic part of the Marvel Cinematic Universe is very much its own thing, something director James Gunn has stated over the years. The good news, though, is that Gunn is involved with "Infinity War," remaining in contact with the Guardians cast throughout filming as well as working alongside the Russo brothers on the project in order to ensure the characters remain true to themselves in the highly-anticipated sequel.
