He was chosen as the best playwright, together with Mehmet Baydın, by the Ankara Art Association for his staging of the play Condolences, the second book of the Mesopotamia Trilogy, in 1984.

His screenplay Dağınık Yatak (Messy Bed) was later filmed by director Atıf Yılmaz in 1986 starring Turkish actress Müjde Ar.
