25 Greatest Movie Musicals of All Time!

25. Once (2006)
Made for less than $200,000, this scruffy indie from writer-director John Carney redefines the musical form. It stars an actual musician — Glen Hansard, of the Irish rock band the Frames — as a fictional busker who falls for a quirky pianist (Marketa Irglova) on the streets of Dublin. They have a tortured romantic flirtation, and pour their hearts out to each other in mournful original tunes that feel utterly real because they're not played as musical fantasy. A must.
