Two hours into their honeymoon, rocket scientist Hugh Marlowe (one of my favourite leading men) and wife Joan Taylor, experience a flying saucer. That’s not a euphemism. The earth is under attack from mistranslated aliens in one of the era’s best sci fis, cowritten by blacklistee Bernard Gordon, George Worthing Yates and Curt Siodmak from the book Flying Saucers from Outer Space by Major Donald E. Keyhoe (retired from the Marine Corps) and directed by Fred F. Sears. Good effects – particularly at the conclusion and a great sense of urgency! – so it’s a pity it was shot in monochrome.
