This is a totally misconceived musical fantasy that never knows what direction it's heading in. Parts of it are sticky-gooey religious drek with heiress Yolanda Aquaviva (Lucille Bremer) graduating from a convent to take her place at the head of the country's richest family. The other story thread concerns grifters (Fred Astaire and Frank Morgan) entering the country (it looks like Bolivia) to escape the American police. With assistance from an archangel (Leon Ames)the stories meet.
Mildred Natwick, as the loony aunt, comes off best in a delightfully comic performance. Ames and Morgan have almost nothing to do. Astaire, with his worst toupee in a major film, seems bored. Bremer (of the twitchy eyes) has almost zero acting talent. The color cinematography and set decoration will knock your eyes out, but as the scenes run from obvious artsy sets to real back drops, there seems to be no consistency or authorial vision.
Aside from a few comic moments (which belong to Natwick) the only things that saves this film from total failure is the musical number "Coffee Time." The set up is a carnival where Astaire and Bremer get pushed into doing a dance together. The oddly syncopated "Coffee Time" catches the viewer off guard because it's so damned good and quite arresting.
The number is introduced by three girls who clap in counter beat to the slightly South American sounds of the main melody. Then swirls of dancers join in, also clapping their four-beat counter tempo. Finally Astaire and Bremer take the spotlight and for a few moments they both come alive as they dance across the amazingly psychedelic floor of black and white wavy streaks. This is a great song/number stuck in a lousy film.
After the song, we resume the dreary narrative. I have no idea what director Vincente Minnelli was trying for, but nothing works. It's not a fantasy, it's not funny, and the religious angle is a total dud. Thank heaven for Mildred Natwick, the color cinematography, and "Coffee Time."
