Director Felix Randau was initially approached to adapt a television series about Felix Kersten, Heinrich Himmler's massage therapist, but grew doubtful of the script's uncritical heroic portrayal. Following independent historical research, Randau recognised the subject's legacy was far more complicated and chose to create his own film instead. 'I Is Another,' which premiered at the Locarno Film Festival this August, depicts a 1952 encounter where a persistent journalist confronts Kersten and his wife to probe the veracity of his publicly celebrated narrative.

Rather than providing definitive answers, the film deliberately preserves uncertainty about Kersten's essential character—questioning whether he should be regarded as genuinely heroic, fundamentally deceptive, or somehow both at once. Director Randau frames the work as engaging with contemporary anxieties regarding factual agreement and narrative authenticity, particularly in light of social media's erosion of shared understanding. The film features a notably European cast led by Danish performer Claes Bang, with supporting roles from Austrian and German actors.
