Mia Hansen-Løve’s fourth feature is a rare achievement: an epically scaled work built on the purely ephemeral, breathlessly floating along on currents of feeling. Eden is based on the experiences of Hansen-Løve’s brother (and co-writer) Sven, who was one of the pioneering DJs of the French rave scene in the early 1990s. Paul (Félix de Givry) and his friends, including Guy-Manuel de Homem-Christo and Thomas Bangalter (otherwise known as Daft Punk), see visions of ecstasy in garage music—as their raves become more and more popular, they experience a grand democracy of pure bliss extending into infinity, only to dematerialize on contact with changing times and the demands of everyday life. Hansen-Løve’s film plays in the mind as a swirl of beautiful faces and bodies, impulsive movements, rushes of cascading light and color (she worked with a great cameraman, Denis Lenoir), and music, music, and more music. Eden is a film that moves with the heartbeat of youth, always one thought or emotion ahead of itself.
