Guy Ritchie’s stylish crime series The Gentlemen brings together British entitled aristocrats to Thai underworld killers in a power struggle over drugs, land and money. To build the world where these characters collide, Ritchie turned to production designer Martyn John and costume designer Loulou Bontemps. The duo spoke with Jeannine Oppewall, the Oscar-nominated production designer behind Seabiscuit and L.A. Confidential, about the “amazing creative rhythm” and occasional aesthetic skirmishes with their “maverick” auteur. Says Bontemps. “He always wants to be surprised and he loves to be challenged.”
