Joseph Cates (Who Killed Teddy Bear?) directed this insipid, widely reviled musical-comedy featuring heavyset comedian Jack E. Leonard in his leaden screen debut as twins Irving and Herman. The plot concerns some teenagers searching for treasure on a tropical island owned by a cosmetics tycoon (Brian Donlevy). His daughter (Jayne Mansfield, a year before her death) heaves her bosom a great deal and sings (badly). The best singing is done by lead teen Jordan Christopher, making his own screen debut with some promising numbers backed by the Wild Ones. There are a number of subplots involving spies, mermaids, and the legendary Fountain of Youth, as well as some amusing interplay between Leonard and Phyllis Diller to keep things interesting.
DVD is in very good condition.
