A Letter to David is a personal film, a cinematic letter from filmmaker Tom Shoval to David Cunio, who was abducted from Nir Oz to Gaza on October 7th and remains captive. David and his brother Eitan played the lead roles in Shoval's award-winning debut film, 'Youth', which centered around a kidnapping and depicted their strong bond. Shoval revisits that film's raw footage, unedited behind-the-scenes material, and auditions, weaving them together in a documentary that serves as both a personal letter and a multi-layered portrayal of the new reality in war-torn Kibbutz Nir Oz, where many were murdered or abducted. This affecting visual journey reflects on what was and never will be again, the cruel separation of the brothers, and the inexplicable connection between life and cinema, memory and reality. The film will not use footage from October 7th but will rely on existing materials to testify to the unimaginable.
