Chris Pratt, James Gunn Talk Ego the Living Planet

At San Diego Comic-Con, it was officially revealed that Star-Lord’s father in Guardians of the Galaxy Vol. 2 is none other than comic book character Ego the Living Planet, set to be played by Kurt Russell in the film. Speaking with Empire, star Chris Pratt spoke about how Star-Lord will react to the news that his father is actually an enormous celestial body.

“You’re going to see these characters having to endure the realities of being in a family,” says Pratt. “You’re talking about a guy who’s been longing to know who his father is for a long time. He’ll discover if that person lives up to the expectations he has in his head.”

Gunn also chimed in with a tease about Ego, and what he’s been doing for the entire existence of the universe, calling him “an ancient cosmic being who has been on the edges of the universe for aeons by himself.”

The Guardians of the Galaxy Vol. 2 cast includes the return of Chris Pratt (Jurassic World, Parks and Recreation) Zoe Saldana (Avatar, Star Trek) as Gamora; Dave Bautista (SPECTRE, The Man with the Iron Fists) as Drax; Vin Diesel (xXx, Furious 7) as the voice of Groot; Bradley Cooper (Joy, American Sniper) as the voice of Rocket; Michael Rooker (Slither, Jumper) as Yondu; Karen Gillan (Doctor Who, The Big Short) as Nebula; and Sean Gunn (Guardians of the Galaxy, “Gilmore Girls”) as Kraglin.
