woman pretends to be blind
a woman who was blind; I remember one scene in which she's filling a glass and her finger is in the glass so she can tell when it's full. Eventually it turns out that she's not blind at all, that she's faking, I think because she suspects her husband of trying to kill her or something. I remember there was a scene in a boat, maybe a sailboat (but it wasn't Dead Calm). There was also a fight scene where one guy unexpectedly turns out to be good with his feet. I don't remember who was in the movie; I'm pretty sure it was an American film.
