Yup. Borderline stalker. It's good they got him to play the role or the romance would've been even more awkward and stalkerish. I guess the logic is that he's an eccentric because of the war, but he clearly had issues before as well.
does anyone know if this was intentional? or was he simply meant to be "quirky"? it's hard to remember what it was like in 1981, if this was truly creepy/stalker behavior. we certainly, culturally, we know a lot more about "stalkers" now than we did then. plus, it seemed to me that he had PTSD; which we also know a lot more about.
Hurt played it good and creepy, but then by the end he was the victim, so we felt bad for him. but, jeez, the first third of the movie or so had me really thinking he was potentially dangerous!
People have pointed out that there is a weird episode of Seinfeld where Jerry happens to show up (he plans the whole thing) at a crush's workplace to ask her out to lunch. I'm not saying it is exactly stalking, but this was the sort of thing was portrayed as normal, quirky, or even romantic at least as recently as 1990.
