"I just got a text message from Steven Spielberg -- so annoying," Pratt joked in the video. "I'll have to get back to you later about Jurassic Park 4."
Five years later, Pratt is just days away from opening night of his summer film, Jurassic World.
"It was a joke that I made," Pratt told ET during the Jurassic World junket.
"I guess it just goes to show that if you read the book The Secret and you put things out there, they all come true," he joked.
At the time when he was fake-texting Spielberg, Pratt weighed about 300 pounds and was yo-yo dieting for roles.
"I was looking into the future," Pratt said. "I was like, 'There's this job. I really want that job. I need to get in shape.' But it was when I saw the movie Zero Dark Thirty for the first time where I was like, 'Damn, I believe that guy is kind of like a believable tough guy.'"
