Pretty terrible Corman quickie shot in Hawaii that even by his pre-Poe shooting standards comes off as a grade Z effort. Mercifully short but not worth the effort. The shark just didn't eat enough of the participants.
Made me realize how little time had passed since film serials like Flash Gordon (as little as between today and The Big Lebowski). Wooden plot, wooden heroes, the exotic Other (who doesn’t speak English very well), European-looking native woman who falls for the hero instantly, badly choreographed fights, et cetera. But the teens at the drive-in double feature was in their cars making out and didn’t even see it.
