Iranian documentary filmmaker Mojtaba Mirtahmasb has been released from Evin Prison after three months in jail. ISNA reports that MirTahmasb, who was arrested on the charge of "collaborating with the Persian BBC network", was released Saturday night on bail of $200,000. Mojtaba Mirtahmasb One of Filmmakers Arrested in Iran -- An Iranian news agency, Young Journalist Club, accused the detained filmmakers of working for BBC Persian and engaging in espionage on behalf of the news service. Report: Iran releases filmmaker Jafar Panahi -- Jafar Panahi, who has won awards at the Chicago, Cannes and Berlin film festivals, was freed on bail of about $200,000, but the report said his indictment would be sent to a revolutionary court for future action. A court in Tehran has rejected Jafar Panahi's attempt to appeal his prison sentence for allegedly making anti-government propaganda films. The court confirmed the original sentence handed Panahi in December last year: a six-year prison term and a 20-year-ban from making films. It has emerged that, just as Panahi's imprisonment took place, he was moving towards making his Hollywood debut with one of the biggest producers in town, and an Oscar-winning screenwriter. To show solidarity with the arrested Iranian filmmaker, Berlin Festival director Dieter Kosslick said he will invite Jafar Panahi to be among the "honored guests" of the 2012 festival. Films by two Iranian directors recently sentenced to jail will be shown for the first time at the Cannes International Film Festival, which opens on May 11 on the French Riviera. An Iranian filmmaker jailed for nearly three months was released Tuesday on $200,000 bail, nine days after beginning a hunger strike, the news agency ISNA reported. According to the sentence handed down by branch 26 of the Revolutionary Court, Panahi has also received a twenty-year ban on making or directing any movies, writing screenplays, giving any form of interview with Iranian or foreign media as well as leaving the country. Iranian film director Abbas Kiarostami said on Tuesday his government's imprisonment of colleague Jafar Panahi is "intolerable," and that film-makers and art in general are under attack in his home country. "This is a catastrophe for Iran's cinema," Hamid Dabashi said. "Panahi is now exactly in the most creative phase of his life and by silencing him at this sensitive time, they are killing his art and talent.
