Did You Know?


All the footage of the principal actors was shot on sound stages at General Service Studios (now Hollywood Center Studios). Only the second unit filming dinosaurs and sloth in Palmdale, Corriganville, and the beach, were on location. All shots of the principals and monsters in the same shot were achieved with rear projection effects. See more »

Ted Osborne: I hate bringing you to a place like this, Carol.
Carole Lane: Don't be silly, Ted. I've been in worse places in New York and I had to pay a cover charge too. Only there, it's called Slumming. I'll survive and love it.

Does not just rely on the dinosaurs
15 September 2008 | by (Hamburg, Germany) – See all my reviews

For 1948, "Unknown Island" is pretty good: shot in colour which was not going to be possible for most monster movies of the next decade, the only problem is the men in monster suits. They move slowly and clumsily and never seem more dangerous than the Muppet Show critters, but then again, also stop-motion and especially "enlarged" lizards have their disadvantages and nothing else was possible at the time.

The story goes like this: a photographer wants to visit an island full of dinosaurs he spotted from a plane. His fiancé agrees to charter a ship. The only man who ever returned alive from the dinosaurs encourages them with the words: "I'll blow my brains out first before I go back to that island!" However, not the creatures become the biggest danger, but the conflicts between the crew, the captain, the photographer, his fiancé and the above mentioned adventurer. Shall they just take pictures, capture one of the monsters - or just run for their lives? "Unknown Island" does wisely not just to rely on the dinosaurs, but also create serious reasons (love, greed, superstition) for arguments and fights between the human beings. Thus it becomes an adventure still worth watching 60 years later even if the effects don't impress anyone anymore. Today we have many movies whose effects do impress - but nothing else does, and that's hardly better.
