Well, I can 100% confirm that the version of Highlander that airs on Hollywood Suite is the U.S. theatrical cut, in all its truncated glory.
It opens on the 20th Century Fox logo. The colour timing resembles the 2010 Blu-ray closest, the print itself is delightfully grainy and shows some dirt but not terribly distracting. The wrestling match B-roll is there, Bedsoe spills his coffee like a dumbass, we don’t see WWII. The original animation is used for the Final Quickening but things get VERY soft and scratchy (which may explain the overhaul in the Director’s Cut).
And finally, the end credits use the original white capitalised font but we don’t get to hear “A Kind of Magic” fade out, instead it cuts to commercial.
I can capture the audio track, but not the high def image yet. I have a DVD recorder but no capture card for HD footage.
