Frozen (2013)
You can tell the strength of a musical movie by the catchiness of its songs, and the fact that the children in the thinly walled apartment next to mine are still singing "Let It Go" definitively proves that Frozen was a force to be reckoned with. While it already has made a whole heap of moolah at the box office, the mind boggles to think how much money is still being made through merchandising.
