Production on the upcoming Queen biopic Bohemian Rhapsody has been abruptly halted due to a "personal health matter" of director/producer Bryan Singer. 

"Twentieth Century Fox Film has temporarily halted production on Bohemian Rhapsody due to the unexpected unavailability of Bryan Singer," a statement released by the studio said on Friday. 

Sources told The Hollywood Reporter that Singer never returned to the production after Thanksgiving due to a "personal health matter concerning Bryan and his family." The BBC reported that the director/producer "hopes to get back to work on the film soon after the holidays." 

Bohemian Rhapsody has been in production limbo for almost 12 years which different directors, producers, and actors planned for the project. Rami Malek will star as iconic Queen frontman Freddie Mercury. The film is expected to hit theaters in December 2018.
