Ok, this is a long shot considering that I don't remember very much at all about this movie. I watched it with my parents like 10 years ago but I've always wondered what movie it was.
I only remember a small part of and the details are somewhat fuzzy but it's about a man who can't die. Full on immortality, doesn't age and can't get hurt (I think) but I have no idea if his immortality is explained. He saves a young girl and takes care of her, and then I think they get romatically invloled when she gets older (maybe they're even married). Eventually she grows old and she's lying on her (death?)bed, and they talk about his immortality and how he's watched many loved ones grow old and die.
And that's about all I can remember. I'm sure it was in English. I'd guess it was made somewhere inbetween 1980 and 1999. Also I'm pretty sure it doesn't take place in present day, at least not when any of this happens. Again, I'm not sure.
After some research I thought it might have been Highlander because the summary on wikipedia states that the character saves a young girl but The rest of the summary didn't seem to fit. I haven't watched it though, so I don't know for sure.
Any help appreciated.
