My own fail-safe M.O. at Tribeca is to concentrate on foreign films (and great parties). My picks this year zero in on North Africa. I recommend “The Aquarium,” Yousry Nasrallah’s enigmatic feature set around Cairo’s landmark grotto (with more hiding places than Hef’s) and “Marina of the Zabbaleen” a gorgeous film about garbage by Tribeca All Access filmmaker, Engi Wassef. Also heard good things about “The Secret of the Grain,” by French academy award winner, Abdellatif Kechiche.
