This patchy, uneven combination of fantasy and musical comedy is hilarious in parts and embarrassing in others, though the premise has great potential in itself -- a screwball Captain Invincible is out to save the world from his nemesis, Mr. Midnight, the white supremacist. Captain Invincible (Alan Arkin) is wallowing in his cups in the Australian outback when he receives an unusual call from the American President asking for his help. Unusual because the Captain had no choice but to go into exile after Joseph McCarthy's Un-American Activities Committee became suspicious of his red cape, and he has never been sober enough to recover from the shock. This history is given in a mock newsreel at the beginning of the film. But now Mr. Midnight is threatening to dismember New York City by convincing all the ethnic groups to live along the seashore. Once they are situated on beachfront property, he will blast out a crack in the earth behind them, cut their connection to the mainland, and send them drifting off into the Atlantic. It seems the dastardly Midnight has stolen the ultra-secret hypno-ray and can slice off New Jersey whenever he wants. Weakened by depression and alcohol, Captain Invincible is nursed back to full throttle by Patty Patria (Kate Fitzpatrick) and is soon ready to zoom over Sydney to the far side of the globe -- after practicing in harness in front of rear-projected scenes. Meanwhile, Mr. Midnight and his sidekick are all set to defend their turf, and their ability to slice it up -- though the (American) patriotic sentimentality that prevails in the end, after several other songs have come and gone, is summarized in a rendition of "God Bless America" that conflicts with the opening scenes and may leave foreign audiences cold.
