I've had this on DVD for quite a few years and have recently bought it on Blu-ray. It was like watching a different film. The colours and the sense of scale are breathtaking, not to mention the excellent score by Bernard Herrmann never sounding better. Younger readers: ignore/embrace some suspect rear projection shots, relax into a slower pace of editing, enjoy the gentle humour and prepare yourself for a classic that still holds up to this day.
