Charlotte Gainsbourg agrees to play a witch thrown to the stake in the first film directed by Béatrice Dalle. However, the anarchic organization, technical problems, and psychotic slip-ups gradually plunge the filming into a chaos of pure light.

A film shoot goes catastrophically wrong in this playful mockumentary from France’s preeminent enfant terrible, Gaspar Noé. Starring a magnificently game duo in Béatrice Dalle and Charlotte Gainsbourg, Lux Æterna is a formally dazzling, mid-length rumination on witchcraft and the filmmaking process.
