The movie market in Cannes, France, this week is such a dramatic sideshow that this year it’s getting its own film. Director James Toback and actor Alec Baldwin are running along Boulevard de la Croisette, filming a documentary on the feverish deal-making that surrounds the film festival. The industry hatches deals in hotel rooms, over drinks at evening parties, and aboard yachts just off the beach. Toback, director of Fingers and Tyson, will document the process of selling a film at Cannes while also trying to land financing for a fictional film. They’re calling the documentary Seduced and Abandoned. The Cannes marketplace — le Marché du Film — is the world’s largest.
