User Reviews

The worst film ever made, easily
8 November 2004 | by (stockholm, sweden) – See all my reviews

I had no idea when I started watching this movie what it was about but I was very well surprised by the extremely low quality of the movie.

It consists of no on screen dialog, a speaker-voice reads an pretensious load of crap as Tor Johnson staggers around as a confused Russian scientist harmed by a nuclear-test. Even if someone for some bizarre reason would WANT to make such an insane movie they would not have been able to come up with something like this.

Only a truly deranged mind could make such a movie. A genius in its own world of badness, competing with brilliant filmmakers like Ed Wood and others but Coleman Francis outnumbers them all!!
