The build up to next year’s release of “Guardians of the Galaxy Vol. 2” has been a tug-of-war between passionate fans eagerly awaiting details, and director James Gunn’s holding them close to his chest. It seems that Kurt Russell is on the side of Gunn -- as he was slim on specific plot information -- but offered some clues, discussing themes of 'family’ and 'complexity’ in a recent interview with Collider.

Speaking at the premiere of his new film “Deepwater Horizon,” Russell appeared to be very enthusiastic about the "Guardians of the Galaxy" sequel, in which he plays Ego, the Living Planet -- Peter Quill’s father. Speaking about the footage he’d already seen, Russell said, “I was impressed with the stuff that I saw at Comic-Con, but they didn’t show you everything [laughs]. It’s a very complex story, and they really get into it.”

The emphasis of the sequel appears to be family. Specifically, Quill’s relationship with his father. "It’s more connected to human issues," said Russell, "family issues, parental issues, and issues that sons and daughters have with their moms and dads … Peter’s character in this one, he’s got dilemmas and he’s got decisions to make that are not just about whether to save that thing or that person. This is about finding out who you are, where you come from, and where you’re going."

Russell echoed his co-stars' enthusiasm for the sequel, suggesting that the film is even better than the original: “I was really impressed that all of the people on the set were so excited because they felt this was so much stronger than the first one.”
