One week after firing Colin Trevorrow as the director of Star Wars: Episode IX, Lucasfilm has emerged with a big-name replacement: JJ Abrams. You may have heard of him. He created a little show called Alias.

Oh, and then went on to work on roughly 4,000 major pop-culture things, including the series-redeeming Star Wars Episode VII: The Force Awakens.

The announcement, posted officially by Lucasfilm on Tuesday morning, added that Abrams will also co-write the upcoming film—and that his writing partner is Chris Terrio. That name will undoubtedly be less familiar to Star Wars fans, but the writer's legacy in film is a little more mixed, containing equal parts good (Argo won him a Best Adapted Screenplay Oscar) and the bad (he had the unenviable job of dragging the awful Batman V Superman script to the finish line).

The film's script may have been the beginning of Trevorrow's end with the project. In August, rumors began to circulate that Episode IX's original script, co-written by Trevorrow and Derek Connolly (who also worked together on the script for Jurassic World), was already facing rewrites in the early going. Its script, according to the Hollywood Reporter, follows a treatment prepared by Episode VIII: The Last Jedi writer/director Rian Johnson. Episode IX is slated to arrive in theaters in May 2019.

Some of the sequel's development turbulence may have revolved around the loss of actor Carrie Fisher in late 2016. Fischer family representatives have indicated that Fisher may appear in Episode IX, though mostly through existing filmed footage and not in CGI form. Reports have indicated that Fisher's character of Leia Organa was set to play a substantial role in the latest trilogy's finale.
