The decision reflected an escalating clash between Singer and actor Rami Malek and was caused by Singer's being missing from the set, necessitating the December 1 production shutdown of the film in which Malek stars as Freddie Mercury, frontman of the rock group Queen, which has been shooting in London.
The producers initially said filming was being suspended because of the director's "unexpected unavailability" but now Singer's contract has been terminated.
Fox confirmed to ABC News that Singer was no longer directing the film, titled "Bohemian Rhapsody", but did not comment on the particulars of the situation.
THRalso claims Tom Hollander briefly quit the movie because of Singer, but eventually returned to the set to continue playing Queen manager Jim Beach.
Rami Malek, as Freddie Mercury, in a scene from "Bohemian Rhapsody". "This was not my decision and it was beyond my control". He cited a "gravely ill parent", and whilst admitting to creative differences at times with Rami Malek, "Rami and I successfully put those differences behind us and continued to work on the film together until just prior to Thanksgiving".
The Hollywood Reporter said that Singer had been warned before production began by two top Fox Film executives, CEO Stacey Snider and President of Production Emma Watts, not to engage in any unprofessional behavior.
Singer has had a long relationship with Fox, directing almost all of the X-Men films (as well as The Gifted pilot).
Much like Solo - which was nearing the end of its shoot when Lord & Miller parted ways with Disney - Bohemian Rhapsody only had roughly two weeks before wrapping principal photography.
Singeralso stated that while he and Malek did clash at points, this was not the main reason he was let go from the project.
