"Frankenstein Meets the Space Monster (1965) is a science fiction cult film, directed by Robert Gaffney and starring Marilyn Hanold, James Karen, and Lou Cutell. The film was released in Great Britain as Duel of the Space Monsters. It is also known as Frankenstein Meets the Space Men, Mars Attacks Puerto Rico, Mars Invades Puerto Rico, and Operation San Juan. In the United States, all of the advertising material, including the trailer, gave the title of the film as Frankenstein Meets the Space Monster. The main title on the film itself is Frankenstein Meets the Spacemonster.
Director Robert Gaffney does a pretty good job; there are a couple of very good uses of freeze-framing, the editing is fairly solid, and even the spaceship interiors are good - you have to look pretty closely to see the wood. Although I did notice that, just as in Robot Monster, we are dealing with Wrinkled Telescreen Technology. Overall, though, this is a fine Bad Movie - one you can enjoy to its fullest while tormenting your friends with it's very existence."
Not much to say about this one other than to brace yourself.
Enjoy the show, y'all!
Have fun with today's Frankenstein crapburger. It's essentially half film, half stock footage, so have fun, ok?
