Movie and reality: the Cunio brothers

When Israeli filmmaker Tom Shoval cast two affable kibbutznik brothers with zero acting experience to play the leads in his 2012 debut crime thriller Youth, he had to employ a drama coach to help turn them into convincing kidnappers.

All throughout their acting lessons, Shoval kept the camera rolling on David and Eitan Cunio with the vague idea of one day making a documentary about the process of teaching newcomers how to act. Instead, those behind-the-scenes clips of the twins from Kibbutz Nir Oz, struggling to evoke the violence of the film’s teenage kidnappers, languished in a desk drawer for more than a decade – until, in a near-implausible inversion of destiny, David himself was kidnapped.

Now those raw clips are emerging for the first time in Shoval’s documentary A Letter to David, which traces the thin line between fiction and fate, present and past, glimpsed through the transcendent bond shared by two formerly inseparable brothers. With footage from the set of Youth and home videos from Kibbutz Nir Oz, set against desolate post-October 7 interviews with the twin who was left behind, A Letter to David is a meditation on a brother's love and the dire reversal of cinema and reality.

“In 2012, you see these coaches trying to teach David how to roughhouse a girl and tie her up because his character kidnaps her, and they were yelling at him: David, you need to be tough, you need to be a kidnapper, you need to act violent’,” says producer Nancy Spielberg. “David replied, ‘it doesn't come naturally to me,’ and then, 11 years later, Hamas kidnaps this person who couldn't even pretend to be violent.”
