You are mistaken, my friend. There was no Highlander II. For some strange reason, it went from Highlander to Highlander 3 with no Highlander II being made.
I will repeat: Highlander II does not exist. Capice?
Word is there is a re-cut edition of Highlander II which, with creative editing, turns the movie into something completely different. I am fascinated by the notion that editing can so deeply change a movie, yet am repulsed by the prospect of returning to such awful material.
