Jonathan Bailey Shares Sweet 'Jurassic Park' Story, Confirms Starring Role in New Franchise Film (Exclusive)

The actor spilled the tea on his role in the new movie while talking with ET Monday evening.

Welcome to Jurassic Park, Jonathan Bailey

On Monday, the 36-year-old actor talked with ET from the season 3 premiere of Bridgerton in New York and confirmed that he will soon be heading up Jurassic World 4, the latest installment in the beloved franchise which celebrated its 30th anniversary just last year. 

"I will be visiting Jurassic Park," Bailey shared exclusively with ET, jokingly adding, "I'm playing a dinosaur."

For the Fellow Travelers star, the new gig -- which comes from the mind of the original Jurassic Park writer David Koepp and Rogue One director Gareth Edwards -- is a full-circle moment as he shares that one of his earliest memories includes seeing the Steven Spielberg hit on the big screen when he was a kid.

"I remember going with my family," he said. "It was the first cinema trip we all went on together. I've got three older sisters so I went when I was like 5."

As for plot details and confirmation on his cast members -- rumored to include Scarlett Johansson and The Lincoln Lawyer star Manuel Garcia-Rulfo, according to Deadline -- the actor kept tight-lipped, but shared that he is feeling ready to take up the mantle and carry on the cinematic legacy left by the previous cast.

"I am really excited," Bailey continued. "For so many of us, I know it's just like an iconic cinematic experience."

The confirmation comes just one day after he teased his involvement in the new project with a cheeky post on Instagram, complete with a photo of him on the Jurassic World water ride at Universal Studios Hollywood.

In the photo, Bailey is seen throwing up peace signs and wearing sunglasses during a visit to the theme park from over a month ago as the photo is timestamped on April 9. He also included a video of a glass of water on a table shaking, a reference to scenes from the original film.

"Hold onto your butts. 🦕," the actor wrote in the caption. 

The last film in the franchise, Jurassic World: Dominion, debuted in June 2022 and starred Chris PrattBryce Dallas Howard and DeWanda Wise, as well as the original Jurassic Park crew including Laura Dern, Sam Neill and Bailey's Wicked co-star, Jeff Goldblum. Deadline reports that none of the reboot actors are expected to return for the fourth installment in the franchise. 

Bailey is having a hot year after the release of Fellow Travelers -- which scored him a Critics Choice Award for Best Supporting Actor in a Miniseries -- his casting in Netflix's Heartstopper, the forthcoming release of Bridgerton season 3 and his starring role as Fiyero in Wicked alongside Ariana Grande and Cynthia Erivo

He stayed similarly quiet on the film adaptation of the Broadway hit, which releases in theaters on Nov. 27, joking with ET that he shows anyone who asks the final cut, including his on-screen family members and friends in Bridgerton. 

"Yeah, I show everyone the whole film," he quipped. "I don't -- I haven't seen it."
