Ilan Klipper enters the world of cinema through documentary filmmaking. His first films are in the tradition of direct cinema: no interviews, no voice-overs. Inspired by director Frederick Wiseman, he co-directs with Virgil Vernier a diptych on the police, Commissariat, which was selected for numerous festivals and broadcast in cinema and on television. His collaboration with Virgil Vernier continues with the short documentary Pandore, shortlisted for the César Award for Best Short Film. He also explores psychiatry with the documentary St. Anne's Psychiatric Hospital, which was broadcast on Arte's Grand Format channel and wins an Award at the Nyon Film Festival.
In 2012, his encounter with singer Christophe leads him to direct Juke-Box, a fictional short film about a fallen singer's attempt to reconnect with creation. The film ends with the recording of a previously unreleased song by Christophe. It wins numerous awards, notably at the Belfort, Clermont-Ferrand and Angers film festivals.
After a foray into the world of justice, with the web series Les Affaires Familiales for Arte, Ilan directs The Starry Sky Above Me, his first feature-length fiction film, a tragi-comedy shot in twelve days. His documentary Tightrope Walkers is part of the 2020 ACID’s Cannes Film Festival Selection.
In 2022, he directs his second feature film, The Peace and Love Process, with Camille Chamoux and Damien Bonnard.
