Don't know if I mentioned it before but when I was down in the depths with this bloody cold [last knockings now] I fancied a good ol' submarine film. So I went to Youtube and typed in my enquiry. Some good stuff came up, and then
Ice Station Zebra [click the link] appeared from the late 1960's. Good Youtube edition, but what was more, it had Overture music at the beginning, and an Intermission [which I entertained by getting a coffee without stopping the downstream] and then Exit Music [obviously from the cinema] once the closing credits had ended. And it was brilliant. I loved it. Made me feel 10 times better. Especially with Patrick MacGoohan in it, doing a superb rendition of a very gutsy, English spy. If only he'd have been chosen for James Bond, he'd would have easily been the best. He was inbetween series of
The Prisoner at the time of the film.
