The Tribeca Film Festival kicked off this week in New York City! The festival, which was founded by Jane Rosenthal, Robert De Niro and Craig Hatkoff in 2002, celebrates the vibrant filmmaking world in New York City, which is why stars are gravitating to southern Manhattan to enjoy the 11 days worth of festivities. Film festival judge Eva Longoria and Mr. Mayhem Dean Winters lunched at the Tribeca Grill Loft for the Juror Welcome event, Zac Posen celebrated the 24-karat gold couture gown he made for Magnum Ice Cream’s short film As Good as Gold with Andrea Riseborough, and Olivia Wilde (in A.L.C.) and Karolina Kurkova (in Blumarine) attended the For the Love of Cinema Filmmaker's dinner hosted by Swiss watch company IWC Schaffhausen at Donna Karan's Urban Zen store.
