There are two weeks of principal photography left, and it is expected Twentieth Century Fox will announce a replacement director in the coming days. Actor Tom Hollander, who is slated to play the role of the band's manager Jim Beach, was also rumored to have left the film due to Singer's on-set behavior, though was persuaded to return.
Sources tell The Hollywood Reporter that Singer failed to return to set after the Thanksgiving holiday break, leaving producers nervous about the state of the production and talking about potentially replacing him.
"Bryan Singer is no longer the director of Bohemian Rhapsody", the film's studio, Twentieth Century Fox, confirmed in a statement to ET.
Despite being over a year away, one of next year's most anticipated movies was quickly pegged to be already Bryan Singer's Bohemian Rhapsody.
Cinematographer Thomas Newton Sigel stepped in and directed a few days' worth of shooting while Singer mysteriously vanished.
The Hollywood Reporter also reports that Singer had been warned before production began by Fox Film chairman and CEO Stacey Snider and vice chairman and president of production Emma Watts that they wouldn't tolerate any unprofessional behavior on his part.
According to insiders, Singer is claiming he is suffering from post-traumatic stress disorder because of the tensions from the on-set drama.
Singer, 52, is best known for directing the "X-Men" films and "The Usual Suspects". The movie is scheduled to be released on Christmas Day of 2018, and Fox is still aiming for that date.
Neither Singer or Malek have commented publicly on the move at this time.
Bohemian Rhapsody now is scheduled to premiere in December 2018.
