aka Red Zone Cuba
How bad is it? It's not the worst Coleman Francis movie, but it's bad.
Should you see it? Sure.
John Carradine sings the title song (in a rather good baritone; certainly better than Chaney's "Spider Baby") and plays a train engineer who tells his story to a reporter. Convicts join mercenaries to invade Cuba, but things go awry. Then, back in the U.S., they throw a guy down a well, then take his car, then a train, then buy another car with a stolen ring, then they go after money in a mine and then they get stopped by the police. It's not as involving or as straightforward as that sounds. There's a couple of decent performances, but the script and filming are bottom of the barrel. Still, it's miles ahead of Francis' "Beast of Yucca Flats." There's a MST3K version, but I haven't seen it.
