Colin Trevorrow co-wrote and directed “Jurassic World” (and is set to direct the follow-up) and will direct Star Wars episode IX. His newest film is “The Book of Henry,” opening tomorrow. We discussed the film’s concept, the ensemble cast, why I’m not allowed at preview screenings, and what exactly an executive producer does. A very educational and informative interview. It’s not every day you get to pick the brain of a top-notch director.
