Hosseini won his first award, Crystal Simorgh for Superstar in 2009. In 2013, he made his directorial debut. In 2020, Hosseini co-founded Pol Media (“pol” translating to “bridge” in Persian) with director Kourosh Ahari and producer Alex Bretow, a distribution and production company aiming to “bridge the gap” between Iranian art, culture and cinema with that of the U.S. He is coming up with the first-ever Turkish-Iranian film, Drunk on Love. He will be in the lead role alongside Hande Erçel, Parsa Pirouzfar, İbrahim Çelikkol, Selma Ergeç, Bensu Soral and Boran Kuzum.
