If you look at Gregory Widen, Peter Bellwood & Larry Ferguson's Highlander screenplay as of 2/6/1985, most of it is nearly 100% identical to the movie (the plot and even the lines).
Everywhere I saw, it was billed as "final".
However, it differs from both US release of the movie, and even the European-release-based Director's cut, in significant ways. Two examples are:
Opening MSG sport was wrestling instead of hockey
Wikipedia mentions that (according to DVD commentary) that was done for a reason.
There was no closing scene where Rachel finds out that MacLeod survives from the fact that Kurgan was listed as the last victim by Moran; and flirts with Moran.
Is there a screenplay version (NOT the novelization) that's "more final" and matches the actual movie?
