Chris Pratt Calls 'Guardians of the Galaxy Vol. 2' the 'Biggest Spectacle Movie of All Time'

— -- Chris Pratt can't say enough about "Guardians of the Galaxy."

The space epic, torn from the pages of an obscure Marvel comic, transformed Pratt from the pudgy punchline thrower on "Parks and Recreation" to a bonafide action movie star, and with a sequel on the horizon, Pratt promises fans have much to look forward to.

The actor, who has parlayed Peter Quill's/Star-Lord's swagger -- and yes, six-pack -- into plum roles in movies like the billion-dollar-making "Jurassic World" and the upcoming "Magnificent Seven" reboot opposite Denzel Washington, gushed to the Toronto Sun. "It’s finished and it’s going to be terrific."

"I’m already so proud of it," he told the paper. "We worked really hard on it and it’s a joy to be part of. ... I think it’s going to be -- I’m not using hyperbole, here -- I think it’s going to be the biggest spectacle movie of all time."

The movie, which again stars Zoe Saldana as the green-skinned assassin Gamora, and the voices of Bradley Cooper and Vin Diesel -- as, respectively, Rocket Raccoon and the tree-man Groot -- opens May 5.

This time around, Pratt's character finds his long-lost alien father Ego, a man-planet played by Kurt Russell.

The creative flourishes of having a character who is a man and also a living planet are just what makes the madcap "Guardians" galaxy "so totally different," said Pratt, who considers himself "lucky" to be a part of the franchise.

"It’s new and exciting and unlike anything people had seen before. There are a lot of superheroes out there, but I think we do something a little different."

"Guardians of the Galaxy Vol. 2" will be released by Marvel Studios, which, like ABC News, is owned by Disney.

"The Magnificent Seven" opens Sept. 23.
