It seems Tom Holland isn’t quite as good at keeping secrets as his alter ego Peter Parker.

During a recent visit to Entertainment Weekly Radio with costar Bryce Dallas Howard, Chris Pratt revealed that it was none other than the Spider-Man: Homecoming star who spoiled the entire plot of Jurassic World: Fallen Kingdom for him.

The young actor spilled the beans while he and Pratt were working on the same lot shooting their respective Marvel projects. As for how he became privy to the top-secret details of the blockbuster franchise, Pratt shared that, “Tom, of course, knows [Jurassic World: Fallen Kingdom director] J.A. Bayona because of the film The Impossible — Tom was the young guy in that movie.”

Soon after Bayona gave Holland a detailed account of the story line, he shared every detail with Pratt. “He told me the whole story, so I heard it right from Tom Holland first. And then when I read the script, I was like, Yeah, he wasn’t messing with me, this is all real.”
