"Kilma" combines two B-movie staples -- the one about the men stranded on a tropical island inhabited by beautiful women, and the one about the tribe of prehistoric women who wear bras and panties made out of animal fur. Two B's obviously don't make an A but "Kilma" is amusing in an unpretentious sort of way and has the kind of casual, unforced narrative drive which most current movies lack.
Frank Brana, (with a tilde over the "n"), makes a somewhat unlikely hero, being about 40 years old and a bit on the stout and hairy side, but there's a certain pleasure in seeing a leading man who doesn't have the face and body of a young Greek god. His beefcake scenes also feature some bondage since, at one point, he's forced down over a rock and whipped on the back, and later he's staked out face-up in spreadeagle style. (The whipping ranks 89th in the book: "Lash! The Hundred Great Scenes of Men Being Whipped in the Movies.")
The women are attractive but tend to be interchangeable.
