Onoda: 10,000 Nights in the Jungle

Onoda: 10,000 Nights in the Jungle (Japanese: ONODA 一万夜を越えて, Hepburn: Onoda: Ichiman'ya o Koete; lit."Onoda: Over ten thousand nights", French: Onoda, 10 000 nuits dans la jungle) is a 2021 war drama film directed by Arthur Harari and co-written with Vincent Poymiro, with the collaboration of Bernard Cendron. It is inspired by the life of Hiroo Onoda (Yuya Endo) a Japanese soldier who refused to believe that World War II had ended and continued to fight on a remote Philippine island until 1974.

It is an international co-production between France, Japan, Germany, Belgium, Italy, and Cambodia. And was particularly inspired by Cendron and Gérard Chenu's 1974 biography Onoda, seul en guerre dans la jungle, Cendron's archives, and Harari's conversations with the author. Harari did not base it on Onoda's own memoir; he considers the film to be fiction inspired by history rather than a biographical book.

The film had its world premiere at the Un Certain Regard section of the 2021 Cannes Film Festival, on 7 July 2021. It was theatrically release in France on 21 July 2021, and in Japan on 8 October 2021. It was received with critical acclaim, winning Best Original Screenplay at the 47th César Awards.
