The Edith Piaf biopic “La Vie En Rose,” starring French actress Marion Cotillard as the sultry Parisian singer, is emerging as the title most likely to generate a bidding war at the Cannes Film Festival. Director Olivier Dahan‘s title already has sold to Japan for a hefty $2 million price tag, sources suggested. “This is the one film that all the German distributors are chasing,” one major buyer said. “It is definitely going to close down here.” Sony Pictures Classics co-president Tom Bernard, who recently picked up the Tribeca Film Festival coming-of-age film “Driving Lessons,” said buyers were “desperate.””There’s nothing out there,” he said. “There’s so much money around, whoever gets picked up is going to hit the jackpot.” Reuters reports.
