The Gaza documentary “NAZA” earned a massive 24.5-minute #VeniceFilmFestival# ovation as the crowd cheered and waved Palestinian flags. This marks the longest-ever standing ovation at Venice, beating the 22-minute ovation for “The Voice of Hind Rajab” last year, and perhaps the longest at any film festival, period. The new documentary was shot at night on the rooftops of Tel Aviv and shows “in detail the systems behind Israel’s calculated mass killing of Palestinian civilians in Gaza,” per an official synopsis. Abraham and Szor interviewed 24 Israeli military intelligence officers and soldiers — all of whom spoke on the condition of anonymity — who were involved in the surveillance or remote killing of Palestinian civilians in Gaza. Their appearance and voices were digitally altered to disguise their identities.
