J.J. Abrams, of course, directed and helped to write the first movie of the new trilogy - Star Wars: The Force Awaken.
J.J. Abrams, who you may know from such films as the Star Trek reboot, Super 8 and a little film called Star Wars: The Force Awakens will be writing and directing Episode IX.
Abrams also will co-write the screenplay with Argo and Justice League scribe Chris Terrio.
"Episode IX" was the second "Star Wars" project to lose a director this year.
It was announced last week that Trevorrow, whose previous films include "Jurassic World" and "The Book of Henry", was stepping aside from "Episode IX".
In June, co-directors Phil Lord and Chris Miller ("The Lego Movie", "21 Jump Street") dropped out of the still untitled young Han Solo movie in the middle of filming, citing "different creative visions".
According to Deadline, Disney and Lucasfilm previously approached Johnson about returning to direct Episode IX, but he declined.

There's no knowing what exactly happened to Thorne, but it's quite obvious that the studio wanted a fresh start for the final chapter of the Star Wars sequel trilogy. The movie absolutely killed at the box office, bringing in an overall total of $2.068 billion.
Episode VIII - The Last Jedi, written and directed by Rian Johnson, debuts December 15. Once Episode IX comes out, we'll really be able to see whether Lucasfilm is all about sticking to the formula and be able to really attribute the success of The Force Awakens where it belongs.
[Director Rian] Johnson shared that information himself during the Japanese press tour for The Last Jedi, saying that Gordon-Levitt's role is "a very brief little thing", but it will be "fun".
