Cult-favorite director Edgar G. Ulmer has quite a disparate cast to work with in Isle of Forgotten Sins. The story is typically brawny adventure fare, concerning a band of hardy South Sea pearl divers. But instead of a group of he-man protagonists, the leading players include the likes of pudgy Frank Fenton, scrawny John Carradine and septugenarian Sidney Toler. They play their parts well, but they aren't terribly convincing as rough-and-ready adventurers. For the record, the plot is motivated by $3 million in gold, which went down to the bottom of the sea during a storm. A second monsoon wipes out most of the cast members, though enough survive for a happy ending. The female cast members are as curiously chosen as the males, with Gale Sondergaard as a cabaret girl and Veda Ann Borg as a villainous native.
