Starring Forrest Tucker, Gaby André, Martin Benson, Alec Mango, Wyndham Goldie, Dandy Nichols and Richard Warner. Screenplay by Paul Ryder, based on the book by Rene Ray (which was a novelisation of the 6-part television series also written by Rene Ray). Directed by Gilbert Gunn and produced by George Maynard.

Also known as COSMIC MONSTERS and THE STRANGE WORLD, this b&w British science fiction horror movie tells the story of experiments with magnetism that unleash cosmic rays that turn a hobo into a burnt-faced strangler and enlarges all the local bugs.

This modest production meanders at an unhurried pace to start with, though it’s interesting to check out the mixed acting styles on show here, with Forrest Tucker, as scientist hero Gil Graham, delivering a dependable performance, whilst most of the Brit actors surrounding him come across as really quite stilted. French actress Gaby André, playing fellow scientist Michele Dupont, injects a little Gallic exoticness to the mix, and Martin Benson adds a smidgen of mystery to proceedings as the visitor ‘Smith’, who turns out to be a Klaatu-like alien on a mission to warn Graham and the others that their meddling with Earth’s magnetic field will have deadly consequences.

After rather too many scenes set in the local pub, the plot thankfully kicks into gear, once all the cosmic ray-affected insects, grubs, millipedes, spiders and even a newt become monster-sized and do battle with soldiers in the woods next to the lab. Woot!

The filmmakers certainly include a diverse bunch of critters in this flick, that’s for sure, including a larval dragonfly and cockroaches. Les Bowie, who supplied the special effects (lots of magnified close-ups of creepy crawlies, etc), does a quite decent job, especially if you consider what little time or money he must have had to bring his low budget wonders to the screen.

The best moment comes when a huge spider fights with a giant cockroach, as the heroine, trapped in the spider’s web, looks on in fear. This sequence is achieved using rear projection, and it looks pretty cool, with tree branches and white strands of prop spider web strung over the rear projection screen, adding a sense of depth and dimension to the visuals. But, when Gil runs up to save Michele, the rear projection image (of the spider) is turned off for some reason, so that the blank rear projection screen can be clearly seen beneath the prop webbing. But, hey, it’s a memorable creature-tastic sequence all the same!

THE STRANGE WORLD OF PLANET X is definitely a cheap and threadbare production, but Tucker brings some much-needed verve to his role, thus preventing the film from becoming too stilted as we wait for the monsters to show up. Along with this production, Tucker also added his gruff, American vigour to the UK-made sci-fi-horror films THE ABOMINABLE SNOWMAN (1957) and THE TROLLENBERG TERROR (1958). The fact that he was in these three flicks means that I can’t help but rate Tucker highly! What a dude!

Ultimately, this movie is worth a watch, as it also features a wobbly flying saucer saving the day by blasting the (model) science lab to bits, and the film includes a brief, surprising moment of gore too, as we see a soldier getting his face eaten by a killer bug!

Finally, this is a COSMIC MONSTERS promotional sheet that used to form part of a Seven Arts Associated binder. Seven Arts Associated was a television syndication distributor and they published a yearly binder in the 1960s, which showed the films that would be available for television airing/syndication. These binders were sent to the television stations. Anyway, I like the COSMIC MONSTERS artwork used for this promo sheet…
