The Horn Blows at Midnight (1991)

A trumpet player in a radio orchestra (Jack Benny) falls asleep during a commercial and dreams he's the angel Athanael. The beautiful angel Elizabeth (Alexis Smith) delivers Athanael to the head of heaven's orchestra, where he's told to return to earth and blow his trumpet at midnight, thus marking the end of the world. When he fails his assignment, he becomes a fallen angel, and though he's given a second chance, his fellow fallen angels conspire to keep him from completing his mission.
