1. 'Eternal Sunshine of the Spotless Mind'
Jim Carrey has a very spotty track record when it comes to non-comedic roles. Anyone remember The Majestic or The Number 23? We didn't think so. But his single greatest work – and easily his most acclaimed movie – is 2004's Eternal Sunshine of the Spotless Mind. Written by Charlie Kaufman, the film concerns a couple that keeps meeting even though they've erased all memories of each other. Part comedy, part bizarre sci-fi romance, it would go on to win the Academy Award for Best Original Screenplay and top many polls of the best movies of the 2000s.
