In this wholly original, self-aware cinematic work, the true crime boom is put under the microscope as filmmaker Charlie Shackleton tells the story of his abandoned documentary about the infamous Zodiac Killer, describing beat-by-beat how he imagined it playing out.

Over vacant Bay Area landscapes, stylised re-enactments and clips from recent true crime hits, his wry voiceover conjures the unrealised project in real time, offering an object lesson in creative frustration — and a hilarious critique of a genre at saturation point.

The ICA presents the London Premiere of the film followed by a Q&A on Saturday 15 November.
