From the mouth of Groot himself, Marvel fans got confirmation of a long-suspected fact: The Guardians of the Galaxy will appear in the next Avengers installment, 2018’s Infinity War. Vin Diesel took to his famed Facebook page for a meandering Facebook Live stream in which he walked outside and rambled about this and that. Around the 20-minute mark, during a meditation on the support of his fans, he talked about how their encouragement helped him get his gig in 2014’s Guardians of the Galaxy, and then added, “Now the Guardians will be included in Avengers: Infinity War and that’s incredibly exciting.†Exciting it may be, but it’s not entirely surprising, given that Infinity War will deal with the cosmic Infinity Stones and the Guardians are the most cosmic heroes of the Marvel Cinematic Universe. This feels like something Marvel didn’t really authorize Diesel to say, but they are mere humans and he is Groot. Fast forward to 20:40 for the confirmation in the video below:
