A team of British astronauts on the first manned satellite into space encounter several problems. First, they're informed the satellite will be carrying a new "tritonium" bomb that is to be tested in space. Then, once they've left the atmosphere, they discover they have a reckless reporter as a stowaway. Then the bomb becomes stuck to the side of the ship and they have to find a way to defuse the bomb before it explodes and kills them all.
A mostly dull but not entirely uninteresting British sci-fi film shot in CinemaScope. It starts off with a quote from Nostradamus, which I found kind of odd for a science fiction film. It's a talky movie without much action. There's a bit of an anti-nuke message but not enough to give this any depth. Lois Maxwell's unlikable character has a bizarre anti-science stance because her brother and father were killed...or something like that. Anyway she basically turns out to be a huge hypocrite, on top of her other character flaws like carelessly endangering the lives of others. She's good at fetching coffee and sandwiches, though. And yes, that's literally what they do with the only female character on the satellite -- have her bring the men coffee and sandwiches. Most of the other characters are bland and forgettable, save for Donald Wolfit's Professor Merrity. It takes awhile before the ship gets off the ground and only then do things get a little exciting. The real saving grace of the movie comes from the special effects work of Wally Veevers, who would go on to work on such classics as Dr. Strangelove, 2001: A Space Odyssey, and Superman.
