Jonathan Bailey not only stars as Dr. Henry Loomis, but also contributes to the film score. He plays clarinet in several orchestral tracks and performs the solo heard during the scene when his character touches a dinosaur for the first time.
Scarlett Johansson has been a huge fan of the franchise ever since she was a child.

A school bus in New York City is seen with "Crichton Middle School" painted on its side. This is a reference to the late Michael Crichton, the author of the Jurassic Park novel that spawned the film franchise.

Gareth Edwards "dropped everything" to direct the film, stating before production, "I was about to take a break and I started writing my next idea for a film and this is the only movie that would make me drop everything like a stone and dive right in. I love Jurassic Park (1993)...so this opportunity is like a dream to me. And to work with Frank Marshall and Universal and David Koepp, who's writing the script, I think they're all legends. So I'm just very excited."
