Film fifteen of the festival and Club Kid is the surprise we didn't see coming. Jordan Firstman's debut is filthy, funny, shot on 35mm in a New York that's already disappearing, and somehow one of the most emotionally honest films we've seen at Cannes. We talk found family, Arthur Russell, Cara Delevingne two inches from a breakdown, and why this is the beginning of a real filmmaking voice. Day four dispatch from the Croisette.
