Director Bryan Singer has left the Queen biopic Bohemian Rhapsody in the middle of production.

A representative for Twentieth Century Fox Film Corp. says Monday that Singer is no longer the director of the film.

The Hollywood Reporter reported Monday that Singer failed to show up to the London set on a number of occasions. Actor Rami Malek who stars as Freddie Mercury in the film complained to the studio about Singer's unprofessionalism on behalf of the cast.

Studio representatives declined to comment on the circumstances surrounding Singer's departure or future plans for the film, which is currently slated for a December 2018 release.

Singer, 52, is best known for directing the X-Men films and The Usual Suspects. Representatives for Singer did not immediately respond to request for comment.
