The film ‘Ice Station Zebra’ is on the TV and was made in 1968. The picture is as good (if not better) as any current production I see on e.g Netflix. How is it so sharp when it was way before the days of HD?

Film has much higher effective resolution than Full HD. The reason old TV was lower quality is related to the ability to transfer enough data in a given time over radio waves. Technology has caught up, and now films can be digitized at their full quality.
