The Valley of the Dragons (1961)

I doubt that this is REALLY lava

Nothing in the movies is real. Even the movie stars in the movies do not look like the actresses and actors who play them.

I don't know, Fred. At 1:33, I think that iguana might be real. At least I think it's real in that shot. Not sure about the scene right before that where he's got somebody in his mouth, but behind the torches? That might just be one.

However, the producers have exaggerated the size. They are not that large. And they eat mostly plants.

And by wild coincidence this forgotten flick was on today just after I came in from mowing the lawn. Sure enough, Joan Staley was there with her stunning figure well exposed during the underwater scene. Great stuff.
