Actually the line you are probably looking for (and why they kept going on and on about "freedom" in
that movie) is:
...for, as long as but a hundred of us remain alive, never will we on any conditions be brought under English rule. It is in truth not for glory, nor riches, nor honours that we are fighting, but for freedom – for that alone, which no honest man gives up but with life itself.

Which, as an aside, has some quite interesting stuff about sacking a King if he isn't good at his job...
[NB This has no real relevance to the current referendum - but I'd be lying if I didn't admit to liking this kind of stuff.]
