From 'Bad Sisters' villain to Himmler's masseur: Claes Bang is back, shocking audiences. His new film, 'I Is Another,' premiering in Locarno, casts Bang as Felix Kersten, the physical therapist to Nazi head Heinrich Himmler. Kersten famously claimed to save lives through his influence. Yet, Bang reveals his 'Bad Sisters' character, John Paul, remains one of his 'worst.' That's a bold claim for a man who massaged a monster.
