"Bohemian Rhapsody" will hit USA cinemas on December 25, 2018.
In announcing the shutdown last week, producers Fox, New Regency and Graham King initially said filming was being suspended because of Singer's "unexpected unavailability".
A source also tells Variety that Tom Hollander, who was set to play manager Jim Beach, left the film to due Singer's behavior.
According to people with knowledge of the incident, cinematographer Thomas Newton Sigel had to step in numerous time when Bryan Singer failed to show up on set.
"With fewer than three weeks to shoot remaining, I asked Fox for some time off so I could return to the U.S. to deal with pressing health matters concerning one of my parents", he said in a statement.
Singer denied the reports and said through a lawyer that he had asked for time off to take care of his sick mother, an ongoing situation that also had affected his own health. Now, The Hollywood Reporter reveals that director Dexter Fletcher (Eddie the Eagle) has been hired by 20th Century Fox to take over.
'Unfortunately, the studio was unwilling to accommodate me and terminated my services, ' he continued.
"The full cast of the film was revealed shortly after, with 'X-Men Apocalypse" s Ben Hardy playing drummer Roger Taylor, 'The Tourist" s Gwilym Lee portraying Brian May and 'Jurassic Park" s Joe Mazzello taking the role of bass guitarist John Deacon. Fletcher also will oversee post-production for the film, which is supposed to release in December 2018.
