But to hear speculation from a ranking Hollywood movie insider with direct knowledge of the productions on both The Book of Henry and Jurassic World (and who requested anonymity out of concern for sensitive ongoing business relationships), Trevorrow’s firing may have come more directly as a consequence of being “difficult.”

“During the making of Jurassic World, he focused a great deal of his creative energies on asserting his opinion,” the executive explains. “But because he had been personally hired by Spielberg, nobody could say, ‘You’re fired.’ Once that film went through the roof and he chose to do Henry, [Trevorrow] was unbearable. He had an egotistical point of view— and he was always asserting that.”

Then, during preproduction on Episode IX, Trevorrow’s relationship with Lucasfilm top brass became reportedly “unmanageable” over the course of “repeated stabs at multiple drafts” of the script.

“When the reviews for Book of Henry came out, there was immediately conjecture that Kathy was going to dump him because they weren’t thrilled with working with him anyway,” the executive continues. “He’s a difficult guy. He’s really, really, really confident. Let’s call it that.”

J.J. Abrams, who launched a new era of Star Wars with The Force Awakens in 2015, is returning to complete the sequel trilogy as writer and director of Star Wars: Episode IX. Abrams will co-write the film with Chris Terrio. Star Wars: Episode IX will be produced by Kathleen Kennedy, Michelle Rejwan, Abrams, Bad Robot, and Lucasfilm.

“With The Force Awakens, J.J. delivered everything we could have possibly hoped for, and I am so excited that he is coming back to close out this trilogy,” said Lucasfilm President Kathleen Kennedy.
