Venom and Eternity is a 1951 French avant-garde film by Isidore Isou that grew out of the Lettrist movement in Paris. It created a scandal at the 1951 Cannes Film Festival.

Experimental film or avant-garde cinema is a mode of filmmaking that rigorously re-evaluates cinematic conventions and explores non-narrative forms or alternatives to traditional narratives or methods of working. Many experimental films, particularly early ones, relate to arts in other disciplines: painting, dance, literature and poetry, or arise from research and development of new technical resources.
