Mehran Tamadon was born in Tehran, Iran, in 1972. He first studied architecture in Paris before turning to filmmaking. He directed his first documentary, Behesht zahra, in 2004. In 2010, he made Bassidji in which he documented his attempts to enter into a dialogue with the Basij militia whose members have dedicated their lives to defending the Iranian regime. The same principle was applied in his film Iranien which won the Grand Prix at Cinéma du Réel and screened in the Berlinale Forum in 2014.
