The Cannes Film Festival requires multiple security checks to access its famed red carpet and there is heavy security along the carpet itself. But this isn’t the first time the security has been breached. In 2014, infamous prankster Vitalii Sediuk slipped past the guards and stuck his head under the dress of America Ferrera during the gala for How To Train Your Dragon 2. Tonight’s protest came ahead of the premiere of George Miller’s Three Thousand Years of Longing, starring Tilda Swinton and Idris Elba. The demonstration comes ahead of Cannes’ “Ukraine Day” on May 21, when the festival will hold a series of events aimed at showing solidarity for the country’s battered film industry.
