To me Highlander is Highlander & Highlander 2 with Fairytale....of which I also consider Lambert's Beowulf to be the unoffical third one, as it has all the makings of a Highlander 3; old Connor, new woman, strangely futurisitic setting, etc. In fact, i've always considered making a fan-edit of it and just doing a few tweaks to make it feel fully like a real Highlander movie, e.g. submitting sampes of MacLeod instead of Beowulf, color-correcting the sky to match Zeist, etc..
But anyways, best of luck!
