From 1966 to 1968 he was a teacher at Tehran's Center for Foreign Language Studies, where he taught classes in literature and English language. He also gave lectures on films and literature at the Center for Audiovisual Studies through the University of Tehran. Early film career 1966–1972 Dariush Mehrjui made his debut in 1966 with Diamond 33, a big budget parody of the James Bond film series. The film was not financially successful. But his second feature film, Gaav, brought him national and international recognition. The film Gaav, a symbolic drama, is about a simple villager and his nearly mythical attachment to his cow. The film is adapted from a short story by renowned Iranian literary figure Gholamhossein Sa'edi. Sa'edi was a friend of Mehrjui and suggested the idea to him when Mehrjui was looking for a suitable second film, and they collaborated on the script.

The film's score was composed by musician Hormoz Farhat. The film was completed in 1969. In the film, Entezami stars as Masht Hassan, a peasant in an isolated village in southern Iran. Hassan has a close relationship with his cow, which is his only possession (Mehrjui has said that Entezami even resembled a cow in the film). When other people from Hassan's village discover that the cow has been mysteriously killed, they decide to bury the cow and tell Hassan that it has run away. While in mourning for the cow, Hassan goes to the barn where it was kept and begins to assume the cow's identity. When his friends attempt to take him to a hospital, Hassan commits suicide.

This was most likely due to Sa'edi being a controversial figure in Iran. His work was highly critical of the Pahlavi government, and he had been arrested sixteen times. When it was finally released in 1970, it was highly praised and won an award at the Ministry of Culture's film festival, but it was still denied an export permit. In 1971, the film was smuggled out of Iran and submitted to the Venice Film Festival where, without
