Yes, you read that correctly, Tom Holland spoiled Jurassic World: Fallen Kingdom for Chris Pratt before the star knew any details about the project. Not only did the Infinity War co-star and Spider-Man: Homecoming actor spoil key moments of the film, Holland also explained the overall story and plot to Pratt as well.
I know what you're thinking, how could Tom Holland possibly have any access to this information? It turns out that Holland has a tight relationship with the sequel's director - J.A. Bayona. Having made his big break on the Bayona film The Impossible, it is likely that Holland's performance in the film assisted in selling Sony and Marvel on his potential as Peter Parker. Since then, the two have kept in touch, with Holland even being used as a stand-in for Liam Neeson's character in Bayona's 2016 adaptaion, A Monster Calls.
In an interview with Entertainment Weekly, Chris Pratt explained how Holland managed to reveal the information on the set of Guardians of the Galaxy Vol. 2.
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.
Watch out, it seems Holland is well past exclusively spoiling Marvel films.
