Well, I'm British and know the film (and have it on DVD - the version I've got came with a lot of extras, including the original moon landing footage). I personally think it's a great film, and although I'm perhaps more likely to remember it because my tastes match with the subject matter, I would have thought those tastes - humour, technology, scientists/engineers as the heroes, the moon landings - would have appealed to a fair few Slashdot readers as well.
As to the person who complained that someone shouldn't be expected to know an obscure foreign film - it isn't a foreign film. Or, at least, if you're writing from Australia, as the .com.au on the address of the article (and the Aussie sounding name of the author of the article) would suggest, it's not.
