Raiders from Beneath the Sea (1964)

This film has to rate badly because the acting and writing are woeful - but as daft action adventure films go, it's not the worst I have ever seen. There is a semblance of a plot - two buddies plan to emerge from the sea clad in diving gear and armed with harpoons, then proceed to rob $250,000 from a bank in an arcade before returning to their watery escape route... It could actually have been a decent germ of a cunning heist, if only the thing hadn't got bogged down in a poor melodrama between a David and Goliath of a couple (Ken Scott and Merry Anders) as she tries to fend off the unwanted attentions of his mate "Buddy" (Garth Benton) and a really dreadful (and I really mean dreadful) soundtrack. Nice shots of the island help a wee bit too, but yes - it's just rotten. Sorry
