Al Adamson, An Auteur of Collages
1 May 2000 | by silentgpaleoSee all my reviews

The line above may be a very kind way of summing up Al Adamson's career, but I feel bad for the guy. When I read a few years back that he had been murdered in his house, I thought,'Who would want to murder this fella?'I have yet to find that answer, and if anyone out there know if there was a trial, or any information on the death of Al Adamson, please contact me at my address.

I have seen a few of Adamson's films, and although his taste is questionable, his movies can tend to be mesmerising. This is sometimes a good thing at 2 in the morning when you are trying to go to sleep; not knowing what to expect, and even as you watch it, you're still not sure.

This is how I saw NIGHT OF THE BLOOD MONSTERS, or whatever the hell that title was. The film contains some of the most boring dialogue scenes since Jerry Warren, and the acting is uniformly wooden. The plot is a bit hard to explain, having something to do with a vampire plague on Earth that, in flimsy exposition, started in outer space. A rocketship and crew (headed by John Carradine) land on the Vampire planet, and encounter more dialogue and tinted Filipino footage.

The Filipino footage that Adamson culled appears to have been done in black-and-white, but since Adamson was making a color film, he came up with a cheap ploy to sell the concept of the tinted portion. It is radiation, explains one of the characters, and the audience is left in total disbelief. In fact, the most unbelievable part is the sets, made up of poorly-lit backdrops and cardboard. The sex scene is hilarious.

This cheesy movie must be seen by any lover of bad cinema, and people who remember what the drive-in was like, or would like to. All others beware, this film is UNCEASINGLY BAD.

Now, if only I could find out what happened to Al Adamson, (and his wife, Regina Carrol, for that matter)...
