Al Adamson was one of the worst filmmakers of the 1960s-70s....much like Ed Wood Jr. Was in the 50s. So imagine my surprise when the IMDB trivia says that the film's title was a ripoff of an Al Adamson title! Wow...talk about setting the bar low! And, this combined with some other trivia (such as the filmmakers running out of money repeatedly and filming as they wrote the thing) lead me to set my expectations VERY low for this movie.

Aliens have come to take over the Earth. But instead of just wiping out people with a plague or ray or space ships, they decide to bring back various monsters and unleash them on the planet. Now considering they reanimate less than a dozen, it would take 158,007 years (more or less) to depopulate the planet! Additionally, while the leader (Michael Rennie) is remorseless and evil, the women that work for him all end up being horny for humans and very emotional.

Occasionally, this film changes abruptly in look--meaning it was pieced together over a long period and, possibly, by different filmmakers and filmstock.

However, this pieced together look is not the problem with the movie, nor are the cheap looking monsters. No, the problem is that the movie is just incredibly boring...making it a bad film that's not even fun to watch in order for a laugh!

In what was his farewell performance Michael Rennie leads a cast of mostly German and Spanish players in a German-Spanish production of Monsters Versus Aliens. Rennie is a rather bloodless alien, reading the lines of this awful film rather bloodlessly.

As an alien scientist who has taken over a deserted abbey for his nefarious experiments, Rennie feels that if we can revive all the old legendary monsters of earth yore, it will panic the earth's populace and the monsters will leave so much destruction that the earth will be relatively easy to subjugate.

Naturally things don't quite work out and if you want to see this film to find out how and why, be warned. Michael Rennie who was in some great films and in one of the great science fiction films in The Day The Earth Stood Still must have needed a paycheck bad to participate in this. He died a year later and I certainly hope he wasn't doing this to help pay the medical bills.

It certainly will be a graveyard smash when Nosferatu (not referred to as Dracula here),Frankenstein's monster, the Wolf Man and the Mummy make their way off the Universal Studio's lot and onto the streets at the bequest of Michael Rennie, once again playing an alien, and this time, not so friendly. He's from a planet which has lost its major energy resources, so he has been sent down to command an army of fellow aliens in destroying or controlling mankind through their own creations of horror, and it's a silly Spanish movie that has to be seen to be believed.

They've changed the Wolf Man legend to where a wolf man can only be killed by a silver bullet shot by the woman who loves them so unconditionally that they are willing to die as well. Apparently the planet Rennie and his gang comes from are lead by bureaucrats as well because it is indicated that they couldn't come down to earth until certain paper work was done.

This cheaply made foreign horror films (featuring an international cast) is horribly dubbed and filled with psychedelic images, dating this instantly. The monsters are not really scary, and the mummy only makes a token appearance. Rennie, in his last film, seems both desperate and embarrassed by being here, and a dumb script just makes this eye rolling throughout. Still, there are some great unintentional laughs, even if the pacing is slow and meandering.
