Bryan Fuller is stepping down as showrunner of Star Trek: Discovery, but remaining as executive producer.
The news follows an announcement in September to push the series by four months to a May launch on CBS All Access series.
Taking over are Gretchen Berg and Aaron Harberts (Pushing Daisies, Revenge, Reign).
Variety reports there has been tension between Fuller and CBS Television Studios, with Fuller dividing his time between Star Trek and American Gods and a reboot of the Amazing Stories anthology.
EW also suggests the $6-7 million per episode price tag has been a source of stress, with Fuller wanting to ensure the series had high quality production values.
In a statement CBS said, “We are extremely happy with the creative direction of Star Trek: Discovery and the strong foundation that Bryan Fuller has helped us create for the series. Due to Bryan’s other projects, he is no longer able to oversee the day-to-day of Star Trek, but he remains an executive producer and will continue to map out the story arc for the entire season.
“Alex Kurtzman, co-creator and executive producer, along with Fuller’s producing partners and longtime collaborators, Gretchen Berg and Aaron Harberts, will also continue to oversee the show with the existing writing and producing team. Bryan is a brilliant creative talent and passionate Star Trek fan, who has helped us chart an exciting course for the series. We are all committed to seeing this vision through and look forward to premiering Star Trek: Discovery this coming May 2017.”
The series will screen in Australia through Netflix.
