I'm trying to obtain some details about a 1979 Adel Emam film. I’m told its Arabic/Egyptian title is "katel ma katelsh hadd" or “qatal ma qatalsh hadd" (roughly "The killer who didn't kill anyone").
I believe that the director is Mohamed Abdel Aziz, but what I’d like to know, please, are the names of the producer and particularly the screenwriter of that film. Many thanks!
