The 10-year-old Room star met the Star Wars icon while walking the red carpet at the LA Film Fest's opening night screening at the ArcLight Cinema in Culver City, California, and he managed to keep his cool exterior even as he was freaking out.
Hamill took the gracious words to heart and retweeted the young star's post, adding, "You (& the entire cast) were wonderful in #TheBookOfHenry Jacob! A beautiful film-so unpredictable, heartfelt & moving #GreatMovie #JediJake."
"He has a very clear agenda" Trevorrow said, laughing. "He's not been shy about that."
From his excitement over meeting C-3P0, R2-D2 and BB-8 at the Oscars to swimming around in a Millennium Falcon inflatable beach raft, Tremblay has been an outspoken Star Wars fan for some time. He even named his adorable dog Rey, after Daisy Ridley's character in The Force Awakens. Check out the video below for more on his adorable obsession.
