This movie mas made to capitalize on the success of Vincent Scotto's "La Java Bleue",a 1938 popular waltz.It's the movie-of-the-song rather than the other way round.The song is heard at least four or five times(or at least an instrumental version) ,but one of them is riveting:Frehel ,who recorded the song ,performs it in a dance hall,and it's the best moment of a rather mediocre flick:Frehel was certainly Edith Piaf's biggest influence.As far as the screenplay is concerned,it's the umpteenth story of a man ,falsely accused of murder and sent to jail;the scene of his escape takes us back to the silent age .That the story is interspersed with music numbers does not help.Old-fashioned acting.
