It looks like Universal and Amblin are finally gearing up to head into production on the Jurassic World sequel, as casting has officially begun for the follow-up to Colin Trevorrow’s hit blockbuster. In addition to returning stars Chris Pratt and Bryce Dallas Howard (hopefully sans high heels this time), Toby Jones and Rafe Spall are being eyed for supporting roles, while the studio is reportedly looking to test actors for two “key roles” relatively soon.

Per Variety, Toby Jones and Rafe Spall are in talks to join Jurassic World 2, which will be helmed by A Monster Calls director Juan Antonio Bayona. Trevorrow is still on board as executive producer and wrote the screenplay for the sequel with creative partner and Jurassic World scribe Derek Connolly. Plot details character specifics are currently unknown, but given Jones’ predilection for playing eccentrics and bad guys (and eccentric bad guys), it’s probably safe to assume that he’s not going to be the nicest dude in the park.

Although no official plot details have been released, we’ve been promised that the new sequel will be much scarier than its predecessor and will feature more practical effects — hopefully that’s good news for those who weren’t particularly blown away with Jurassic World, despite the film’s massive box office success.

Jones most recently starred in the sci-fi thriller Morgan and reprised his role as David Pilcher on Season 2 of FOX’s Wayward Pines. He appears in an upcoming episode of Sherlock, and stars in two 2017 thrillers: The Coldest City with Charlize Theron, and The Snowman with Michael Fassbender. Spall is recently best known for roles in the Black Mirror episode “White Christmas” and Prometheus, and also starred on the short-lived Showtime series Roadies.

The Jurassic World sequel will hit theaters on June 22, 2018.
