Musicals adapted from movies (not to be confused with musical movies) are a common sight on Broadway these days. Some purists treat this trend as nigh apocalyptic, but classic shows have always been adapted from other sources: books, plays and even, yes, films. We've combed the history of the latter category to devise this list of the 30 all-time best movie-based musicals, with trailers for the original films tacked on as a bonus. Our criteria varied, but relevant factors included: staying faithful or making improvements to the source; cleverly translating a story from the language of cinema to that of musicals; and working on its own terms as theater. Some shows that might seem to belong on this list couldn't technically qualify—such as La Cage aux Folles (based on Jean Poiret's play) or The Light in the Piazza (based on Elizabeth Spencer's novel)—while others just barely missed the cut. What are your favorite movie-theater hybrids?
