CANNES, France (AP) — Before this week, the dissident Iranian filmmaker Jafar Panahi hadn’t attended the premiere of one of his films in more than 15 years. Panahi, one of the leading international directors, was banned from traveling out of Iran in 2009 for attending the funeral of a student killed in the Green Movement protests, a judgment later extended to two decades. But even when placed under house arrest, Panahi kept making movies, many of which are among the most lauded of the century.
