Immediately after that he directed and produced his masterpiece, Downpour (Ragbaar). Since then he has produced and directed eight other movies and has made significant contributions to the development of cinema and theatre in Iran. Despite his popularity, Beyzaii has never been successful in gaining the support of the government, either before or after the revolution. After close to twenty years, two of his films, Death of Yazdgerd and Ballad of Tara, have still not been able to receive a screening permit due to their conflict with the Islamic code used in the Iranian motion picture industry. Beyzaii's Bashu, the Little Stranger, about a little boy who loses his home and family to the war, was also threatened with censorship and received a screening permit only after the end of the Iran-Iraq war.
