I was thinking mostly of old school sailships, the kind used in the napoleonic wars and before, such as are featured in master&commander and hornblower, but thanks for the other tips anyways. Incidentally, I'd seen most of the films anyways, except for das boot. That's about a boat during WWII transporting heavy-water or something, isn't it? I think my class saw that in high-school, but I was sick that day.
I'm not sure I've seen "Mutiny on The Bounty", but I just finished watching "The Bounty" with Mel Gibson, so I'm guessing it's a different filmatization of the same incident.
Is it confirmed that they are making a sequel to Master & Commander? Last I heard, Russel Crowe was tweeting that people should email some guy at some studio who was the decisionmaker if they wanted to see it made. Essentially that they own the rights and they know the novels are an untapped well of great material, but that they are reluctant to make a sequal because the first one, despite generally doing well, didn't create enough hype for the sequal to live on that alone.
Anyways, thanks for the suggestions, many of them I have seen (and liked a lot), and I'll try to check out the ones I haven't, but if anyone has any other recommendation of naval films from back when they used sailships, I'd appreciate it. Thank you.
