Release

Some controversy surrounded the film's poorly planned release at the Cannes Film Festival. Goskino did not allow it to be shown. But the festival's managing director, Maurice Bessy, was sympathetic to Tarkovsky, and upon hearing that Mirror was not allowed to be shown, he threatened not to show any other Soviet film. Mirror never had an official premiere, only a limited, second-category release with just 73 copies. It was officially announced for September 1975, but was shown as early as March 1975.
