Cannes returns this year with a lineup of international heavy hitters such as Lars Von Trier ("Manderlay"), Jim Jarmusch ("Broken Flowers"), Atom Egoyan ("Where the Truth Lies"), David Cronenberg ("The History of Violence"), Wim Wenders ("Don't Come Knocking"), and Gus van Sant's ("Last Days"). With a "return to recognized mid-career international directors without treating the festival like a shrine to cinematic styles of the past," Iam Lacey (for the Globe and Mail) examines this year's lineup and the festival's ongoing struggle for relevance.
