"Now, the Guardians will be included in Avengers: Infinity War and that's incredibly exciting", he told his fans.
In a recent livestream on Facebook (via Comic Book Resources), Vin Diesel (who plays Groot in Guardians of the Galaxy and its upcoming sequel) talked a bit about how the Marvel cinematic universe is coming together.
As for story lines, fans wonder whether the fourth Avengers film could cover the Infinity Crusade arc, but The Avengers: Infinity War would need to set-up a ton of backstory should its sequel wish to tackle that specific story.
The real goal of the video was not for Diesel to break news about the Marvel Cinematic Universe, but to show off an award he received from Facebook for having over 100 million fans.
The Russo brothers, who are directing the third Avengers flick after proving to have the golden touch in their previous MCU outings, admitted as much earlier this year while playing coy about who exactly would be in the movie's large cast. Joe Russo told the site.
We all knew it was enevitable, but the Guardians of the Galaxy have officially been confirmed for Avengers: Infinity War by Vin Diesel himself, during a Facebook live stream. Anthony Russo added, "You'll learn that, but not for quite some time".
"In time, we will reveal what the second film is", Joe said, dashing fans' hope for a more immediate explanation.
Avengers: Infinity War will feature more Marvel superhero characters than any film before it. It will definitely be interesting to see what screenwriters Christopher Markus and Stephen McFeely concoct to balance what is shaping up to be an enormous ensemble. XXx: Return of Xander Cage will premiere a couple of months earlier, on January 20, with Avengers: Infinity War scheduled to be released a year later, on May 4, 2018. I'm putting in my suggestion here and now: dance-off between the Guardians and the Avengers.
