LOS ANGELES — Guardians of the Galaxy Vol. 2 won’t hit theatres until next month, but Chris Pratt is already teasing big things for his intergalactic band of misfits when they return in next year’s Avengers: Infinity War.

“It’s exactly what the fans want,” Pratt tells Postmedia Network. “I’ve heard over and over from people, ‘When are the Guardians going to meet up with the Avengers?’

“I was never sure how that would happen or if that would happen, but then they announced it and called us and told us it was happening. We’ve shot most of it — my stuff — and I can tell you, the fans are not going to be disappointed. It’s going to be really freaking cool.”

Directed by Captain America: The Winter Soldier and Civil War filmmakers Joe and Anthony Russo, Avengers: Infinity War and 2019’s untitled Avengers 4 mark the culmination of the Marvel Cinematic Universe that kicked off with 2008’s Iron Man.

“It’s been a long time coming,” Pratt says of the sequels, which are being shot back-to-back. “This is a decade’s worth of deep storytelling that all leads up to this thing.”

While promoting The Magnificent Seven at the Toronto International Film Festival last fall, Pratt described Guardians of the Galaxy Vol. 2 as the “biggest spectacle movie of all time.”

“Well, so far, Guardians of the Galaxy 2 still is the biggest spectacle movie of all time — that is all time up until now. But Avengers (Infinity War) is going to be a pretty big spectacle. I think you’re talking 40 heroes — that is a huge spectacle.”

Guardians of the Galaxy 2 opens May 5.
