Screenwriters rarely develop a distinctive voice that can be recognized from movie to movie, but the ornate imagination of Charlie Kaufman ( Being John Malkovich, Adaptation) has made him a unique and much-needed cinematic presence. In Eternal Sunshine of the Spotless Mind, a guy decides to have the memories of his ex-girlfriend erased after she's had him erased from her own memory--but midway through the procedure, he changes his mind and struggles to hang on to their experiences together. In other hands, the premise of memory-erasing would become a trashy science-fiction thriller; Kaufman, along with director Michel Gondry, spins this idea into a funny, sad, structurally complex, and simply enthralling love story that juggles morality, identity, and heartbreak with confident skill. The entire cast--Jim Carrey, Kate Winslet, Kirsten Dunst, Elijah Wood, Mark Ruffalo, Tom Wilkinson, and more--give superb performances, carefully pitched so that cleverness never trumps feeling. A great movie. -- Bret Fetzer
