After several unauthorized Iranian films gained international attention this year, the government has announced that it will punish filmmakers who do not obtain approval for their work, Agence France-Presse reported. “No One Knows About Persian Cats,” a film about the underground music scene in Iran from the director Bahman Ghobadi, right, which won a jury award in Cannes, is just one of several films that has provoked a crackdown on directors and actors in the country. “I announce that we will take action against artists who collaborate in producing unlicensed films,” Alireza Sajadpour, head of the culture ministry’s vetting office, said in the English-language Tehran Times on Sunday. Productions in Iran are subject to review before being released there, and directors are expected to submit screenplays for approval before beginning shooting, though some ignore the process.
