Before a special screening of Guardians of the Galaxy Vol. 3 at the IPIC Theater Fulton Market in New York City on Wednesday, Pratt opened up to PEOPLE about his relationship with the Terminator star. "Arnold's support means the world to me on a couple different levels. Just being his son-in-law and being part of his family, it obviously means a lot to have his support," began Pratt, 43. "But then on another level, just being somebody who grew up loving his movies, the big action hero — I dreamed of being Commando and dreamed of being the soldier from Predator, and I loved Terminator," he added. "So him to give me kudos for going out and being on the marquee is really kind of mind-blowing."

Pratt described how he's changed after 10 years of playing his character to PEOPLE. "The heart of this character, the soul of this character, has always been mine," Pratt said. "That divine spark that is in me is also in this character." He continued, "His different set of life experiences and the circumstances that created him make him different than me, and in the past 10 years, the circumstances that have created me make me different than who I was 10 years ago in that way." "So I'm not sure it was so much Star-Lord that changed me — although being cast as Star-Lord has certainly had a profound impact on me and how I manage day to day. And how my grandchildren will be able to go to college," he joked.
