Rumours about Spanish filmmaker Juan Antonio Bayona directing the sequel to “Jurassic World” are now true. The director confirmed his involvement on the fifth “Jurassic Park” film on Twitter. Colin Trevorrow and Steven Spielberg will produce the movie based on a script by Trevorrow and Derek Connolly.

“It’s official! So excited to join the Jurassic Team!!” wrote Bayona on his Twitter page. Trevorrow and producer Frank Marshall also announced the news on their Twitter profiles. “Proud to collaborate with one of my favorite filmmakers on the next Jurassic adventure. JA Bayona, it’s all yours,” Trevorrow said. “Jurassic World” producer Frank Marshall said “Thrilled to announce JA Bayona is on board to direct JW2. Welcome to the team @FilmBayona!”

Other celebrities also congratulated Bayona on Twitter. “God Bless Bayona!” said director Guillermo del Toro, while Bryce Dallas Howard wrote, “@FilmBayona And so it begins … ” Howard will reprise her role as Claire Dearing in the sequel along with Chris Pratt.

J.A. Bayona is a relative unknown in Hollywood. His first full-length feature was the 2007 Spanish horror film, “The Orphanage.” His second major feature was the tsunami drama “The Impossible” in 2012. It was based on the true story of the struggle for survival of a tourist family in Thailand in the aftermath of the 2004 Indian Ocean Tsunami. It earned lead actress Naomi Watts a Best Actress Oscar nomination.

Bayona’s latest project before  “Jurassic World 2” is the fantasy drama “A Monster Calls.” It stars Liam Neeson, Felicity Jones, and Sigourney Weaver among others. “A Monster Calls” tells the story of a boy (Lewis MacDougall) who seeks the help of a monster tree (voiced by Neeson) to cope with his mother’s (Felicity Jones) terminal illness and being bullied at school. It will be released on October 14.

Trevorrow had hinted last year that Bayona might direct the Jurassic World sequel when he told Philippa Hawker of the Sydney Morning Herald. “I want to see what a cool Spanish horror director’s Jurassic Park would look like.” Bayona was attached to direct the “World War Z” sequel but left the project. It is then that rumours of his directing “Jurassic World 2” began to circulate.

No story details for “Jurassic World 2” are known. Trevorrow had told Wired UK earlier that it will not be about “just a bunch of dinosaurs chasing people on an island. That’ll get old real fast.” Another unconfirmed rumour appeared that London was being scouted as a location for the Jurassic World sequel. Best guess is the story will follow Dr. Henry Wu (B.D. Wong) who escaped Isla Nublar with many dinosaur embryos to an undisclosed location.

According to IMDB and THR, Patrick Crowley and Thomas Tull of Legendary pictures are returning to produce the film. Belén Atienza is joining them. Dr. Jack Horner, the palaeontologist consultant on all “Jurassic Park” films, is returning as well. Based on Bayona’s resume, “Jurassic World 2” is expected to be darker with horror elements, like Spielberg’s first “Jurassic Park.”
