Hold on to your butts!

Even before “Jurassic World: Fallen Kingdom” arrives in theaters June 22, Universal Pictures announced plans Wednesday to release a follow-up, “Jurassic World 3,” on June 11, 2021.

Screenwriter Emily Carmichael will join Colin Trevorrow on the script for the third installment in this new series of “Jurassic” films, working from a story by Trevorrow and Derek Connolly, who cowrote “Jurassic World” and “Fallen Kingdom.”

Trevorrow directed “Jurassic World” before turning those duties over to J.A. Bayona (“A Monster Calls”) for “Fallen Kingdom.” There’s no word yet who will helm the third film. Trevorrow and “Jurassic Park” director Steven Spielberg will also return as executive producers.

Carmichael’s credits include co-writing the upcoming “Pacific Rim: Uprising” and reworking the long-gestating “The Black Hole” remake for director Joseph Kosinski (“TRON: Legacy”).

“It’s important to this franchise that we welcome new creative voices to keep our storytelling fresh and alive,” Trevorrow said in a statement. “I’m thrilled with the tension and beauty J.A. has brought to ‘Fallen Kingdom,’ and I know Emily will add another layer of emotion to the concluding chapter of our trilogy.”

“Jurassic Park,” of course, ushered in a new era of visual effects upon its release in 1993, creating photo-realistic dinosaurs through a combination of practical and computer-generated trickery.

In 2015, “Jurassic World” outgrossed all three of its predecessors, with more than $1.6 billion in worldwide receipts. “Jurassic World 3” will complete Trevorrow’s cycle of films, but if “Fallen Kingdom” comes even close to the massive haul of its predecessor, don’t count on it being the last one.
