Je t'aime, je t'aime is a 1968 French science fiction film directed by Alain Resnais. It was listed to compete at the 1968 Cannes Film Festival, but the festival was cancelled due to the countrywide wildcat strike that occurred in May 1968 in France.
As with Chris Marker's La Jetee, a man is selected to participate in time travel experiments to his personal past. However, due to equipment malfunction, he experiences these events out of chronological sequence, cause and effect.
