Not from the 80s, 1993 to be exact, but the movie Death Ring
comes to mind. In this, though, the girl is the hunted's fiance. It stars Chad McQueen, Billy Drago, Don Swayze, and Mike Norris; a.k.a. Who's your more famous relative.
It's been a while since I have seen it, so I don't remember if there was a hunter in a harlequin mask or not.
Might be nice if I included the IMDB Listing
