Legendary avant-garde filmmaker Alain Resnais (Last Year at Marienbad [review]) applies his experimental technique to time travel in the 1968 film Je t'aime, je t'aime.
After a failed suicide, a man (Claude Rich) is sent one year in the past for one minute to see what change he might bring about. A malfunction in the machine strands him, however, and he jumps around the timeline from memory to memory.
With each new moment relived, Resnais brings the story a little more into focus, ultimately revealing why the man took a gun to his head.
Je t'aime, je t'aime requires your full attention, but the effect is like watching a mural come together, each stroke of the brush bringing the tableau closer to life.
