It'll be hard to deny it: the Cannes Festival doth Iranian cinema love. Asghar Farhadi's "Everybody knows," which stars Penelope Cruz and Javier Bardem, will open this 71st edition, in a long tradition of showing deference to Iranian cinema. Jafar Panahi, under house arrest in Tehran by order of Iran's judicial courts (he won the top prize at Berlinale for his "Tehran Taxi" in 2015), has a horse in this race, too: his film is called "Three faces."
