Philip Kaufman achieves a delicate, erotic balance with his screen version of Milan Kundera’s “unfilmable” novel. Adapted by Kaufman and Jean-Claude Carrière, the film follows a womanizing surgeon (Daniel Day-Lewis) as he struggles with his free-spirited mistress (Lena Olin) and his childlike wife (Juliette Binoche). An intimate epic, The Unbearable Lightness of Being charts the frontiers of relationships with wit, emotion, and devastating honesty.
