Chances are they probably all are.

I wouldn't be so sure about that. Subtitles from that era tend to be "summarised", in that whole sentences are re-worded in order to keep the subtitles on screen for longer, as there was the belief at the time that people would not be able to read the subtitles at the same speed as what was being said on screen. These days that style looks odd and we're much more used to subtitles accurately reflecting what people have said on screen.
