Interesting and inventive fifties monster movie
27 October 2008 | by (Beverley Hills, England) – See all my reviews

I'm not a big fan of fifties monster movies in general, but this one is pretty decent. The film was directed by Riccardo Freda, although he was going under the pseudonym 'Robert Hamton' in order to fool audiences into thinking that the film was an American picture. The film does take obvious influence from the American monster movies and is similar in style, plot and execution; and actually credit does have to go to Freda in that respect as if it wasn't for the awful dubbing, one would have no reason to think that this wasn't an American film. The plot is rather well worked and focuses on the demise of the Mayan civilisation. We focus on a team of archaeologists studying some ancient Mayan ruins when they come across a cave which houses a lake. After diving into the lake, they discover that it is full of gold; although things go a bit awry when they also find out that the lake is inhabited by an ancient blob-like monster. They end up taking part of the creature back to the lab where upon studying it, they realise it could threaten the whole world...

It was unveiled that many of the films which Riccardo Freda took credit for were actually directed by his young apprentice, Mario Bava - and Caltiki is one of those films. I have no idea how much of the film was directed by Bava, but I'd hesitantly say that I think it was mostly done by Freda as the film does not feature much in the way of Bava's trademark styling's; although in truth the filming style is all very by the numbers and there's not a lot of room for stylish visuals. The plot is well done, however, and is certainly more inventive than I thought it might be. The special effects are not particularly spectacular; though they certainly are serviceable for the type of film and are used well. There are a handful of good ideas on display - the fate that awaits a particularly greedy archaeologist being one of the best parts of it. The film tries to a bit spectacular towards the end, and it does work somewhat, although many of the American pictures did the spectacular ending better. Still, this is a decent little monster movie and I'm sure fans of this stuff will enjoy it.
