Did You Know?


The two-legged dinosaurs (ceratosaurs) were rubber suits worn by actors in the desert of Palmdale, CA. When the explorers shoot grenades at them, one of the beasts falls down, apparently dead. The actor inside the suit actually fainted from the extreme heat, and the director decided to use the footage. See more »


[first lines]
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.

You can't go home again, or to a Saturday matinee for twenty-five cents either.
6 March 2004 | by (Fresno, California) – See all my reviews

I saw Unknown Island when I was eight years old, packed into a Saturday matinee in a tiny theater in a little California town with a bunch of my buddies. The movie didn't drive us from the theater in fear, but it was scary enough, and fun enough, that its plot devices became themes for a summer of children's pretend games of dinosaur hunts and battles against giant sloths. The sexual undercurrents of the film were lost on us: bring on the prehistoric beasts!

I never expected to see it again, but a browse through the Netflix library turned it up, and I couldn't wait to be disappointed! Of course I was, but so what? It was worth the repeat viewing just to be reminded that there was a time when my imagination could overcome cheesy production values, silly dialogue, and incoherent plotting. Movies are magic, especially for the young. Unknown Island made me long again, if only briefly, for a bag of stale popcorn, a Big Hunk candy bar, and a Captain Marvel serial.

And for another summer of games in the woods, running after, or away from, those pesky dinosaurs.
