First-time filmmaker Angela Ismailos jets around the globe, scoring priceless face time with Bernardo Bertolucci, Catherine Breillat, Liliana Cavani, Stephen Frears, Todd Haynes, Richard Linklater, Ken Loach, David Lynch, John Sayles, and Agnes Vardas. With a talent pool like that, Ismailos can’t go wrong, though her choice of interview subjects is so random and the discourse so broad that this 2009 documentary never really arrives anywhere; like one of those Oscar montages of classic films, it delights from start to finish and then evaporates. “I wasn’t exactly sure what it was I was hoping to discover,” she confesses in a voice-over, just before the answer appears onscreen: A Film by Angela Ismailos.
