How The Day the Earth Stood Still has been received, argued over, and remembered.
A prestige hit in 1951 — it even won a Golden Globe for promoting 'international understanding' — at a moment when most alien-invasion pictures were drive-in cheapies. Its stature has only compounded since: National Film Registry, AFI lists, and near-universal agreement that it's the crown jewel of Golden Age sci-fi.
The perennial dust-up is whether its earnest cold-war sermon is timeless moral clarity or a finger-wagging lecture — a debate the widely panned 2008 Keanu Reeves remake settled mostly in the original's favour.
'Klaatu barada nikto' may be the most famous line of untranslated dialogue in movie history — quoted in Army of Darkness, and Klaatu, Barada and Nikto turn up as alien names in Jabba's palace in Return of the Jedi. Bernard Herrmann's theremin score basically invented the 'sound' of aliens for a generation of films.
An unshakeable 'you must have seen this' pillar of the 1950s sci-fi canon — the respectable one your film-snob friend allows onto the list.
