Check out this video for the Japanese movie Fish Story. There's a good review here on the Cinematical website. The plot is a very interesting one:

Quote:
"Rather than a fish, or fishes, the linchpin of the narrative is a song entitled "Fish Story," recorded by an obscure Japanese punk band in 1975 (one year before the Sex Pistols were formed). Unappreciated in their own time, the band's song takes on a life of its own over the years, still entrancing listeners in a record store in 2012. A comet is about to strike the earth, and mankind only has five hours left to live. With the rest of the populace departed to supposedly safer high ground, three men come together, listening to the record and fantasizing that, somehow, the song will be able to save the world."

By the way, that's Kora Kengo featuring as the lead singer.
