The American Pavilion — the big white schmooze tent on the beach at the Cannes Film Festival — has been re-christened as AmPav to discourage notions that it’s only for Yanks. “More than 40% of our membership is made up of journalists and industry professionals from countries other than the U.S.,” founder Julie Sisk has proclaimed. And something else has changed. Last year it cost $25 bucks to buy an advance entry into this well-run establishment — this year it’s been doubled to $50 in advance and $100 on-site. It’s still worth it but whoa.
