I know that this film can be regarded as something of a classic 50s sic-fi movie, but my word is it bad. The opening, pre-credit sequence is actually very impressive but my advice would be stop it there as you've seen the best of it and save yourself the agony of the awful acting and terrible dialogue. Yes the film does predict some technological advances that at the time of its making could only be dreamed of but these are mere pretty window dressings to the crass performances and wafer thin story. Clearly based on a hackneyed story of a bullying commanding officer going loopy and leading his charges to the brink of disaster, the crew of the first manned mission to Mars seems largely to be made up of second rate Sergeant Bilko cast offs. These days, the cartoony personas, which may once have seen humorous are now just toe-curling and I wouldn't trust this lot to be able to organise a trip to the supermarket never mind land on the red planet.
