The trailer for Highlander: Endgame has a lot of supernatural elements that have never been in the series before, and were missing from the final film.
The things that aren't even close to the final movie:
- Jacob Kell is described as a "supernatural enemy", which fits for all the magic stuff we see him do in the trailer, but not in the film where he's just like everyone else
- Connor MacLeod slices his sword through Kell and he splits right down the middle, reforming into two separate people
- Duncan and Connor emerge from some sort of mystic portal
- A sword is thrown at Kell, and he stops it with telekinesis
- Duncan and Connor are facing each other and their swords levitate from the ground into their hands.
- Kell has Connor's head (his soul?) in a crystal ball, which he then shatters
There's also some minor changes that seem more in line with the standard changes any film might experience between trailer and final cut.
I find this baffling because the tone of the final cut of the movie is pretty close to that of the earlier films, and it lacks any sort of supernatural magic besides the initial conceit of the Immortals. Kell is powerful, but he's also got the same abilities as any other Immortal. If they intended to match the tone all along, I can't understand why they would bother to shoot these scenes.
Why is the trailer for Highlander: Endgame so radically different from the final film?
