The IMDB review of the 1980 movie, "Can’t Stop The Music," puts it as well as I can:
Rarely in the history of mankind have we seen a movie so incredibly awful that it becomes a "must-see film".
Indeed. It is jaw-dropping to think of this vehicle for the Village People – starring Steve Guttenberg and athlete Bruce Jenner – as a serious, big budget movie. But it was, and everyone so far as I can tell is in denial about who the Village People really were. The finest scene is probably the one below. On Washington’s Gay Pride weekend, I might as well engage in some can’t-help-myself shame.
