Scheduling is being cited for the exit, as Goyer keeps a busy TV schedule as executive producer on SyFy's Krypton and is working on an adaption of Isaac Asimov’s Foundation trilogy as a miniseries. Other sources cite the magnitude of the big-budget project, as Goyer hasn't helmed a feature film since 2009's $16 million-budgeted The Unborn.

The Masters reboot is based on the popular Mattel toyline that spawned an animated TV series (1983-85) as well as a 1987 movie starring Dolph Lundgren. The reboot has seen other filmmakers come and go during its development, including G.I. Joe: Retaliation director Jon M. Chu and McG.

Mattel is a partner in the movie, and Sony's Matthew Milam will oversee for the studio. Escape Artists' Todd Black, Jason Blumenthal and Steve Tisch are producing with Franklin Entertainment's DeVon Franklin.

The film has a release date of Dec. 18, 2019,
