Goyer, an executive producer on the show and one of the writers behind Batman Begins and The Dark Knight, will still be involved with the production but is leaving behind the day-to-day duties to focus on films and directing, according to an ABC spokesperson. A new showrunner has not yet been determined.
"As my feature projects have started ramping up again, I felt I was being pulled in too many directions," Goyer said in a statement. "I'm proud of the show and excited about the relaunch. It's in great hands."
The move comes less than five months after the freshman series' first showrunner, Marc Guggenheim, left the series. Since premiering in September to 14.5 million viewers, the sci-fi drama has dropped notably in the ratings. The series' last new episode in December was watched by 7.3 million viewers.
