Sheesh! What a dreadful movie. Dodgy camera work, a script with more corn than Kellogg's, and acting so hammy you could open a pig farm with it.
To cap it all, it doesn't know which audience to aim at - we have Cornel Wilde - or is that Corny Wilde? - getting on his soap box about the hazards of smoking any time someone lights a cigarette, dear oh dear, and in another awkward scene we have the baddie, Lobo, forcing his, ahem, if you will, 'male friend' to do a striptease dressed in a bikini. Try explaining that one to the kids...
Throw in an overly contrived Treasure Island-cum-Jaws type storyline, and the result is a film so unintentionally funny, it's enjoyable - I shouldn't expect a Special Edition DVD any time soon, though.
