Visible crew/equipment: There is a shot where the taxi is on the bridge going into NYC, and when the camera that is tracking the taxi pans, we catch the corner of the truck that the camera is mounted on.
Highlander: Endgame (2000)
1 visible crew/equipment mistake
Directed by: Douglas Aarniokoski
Starring: Christopher Lambert, Adrian Paul, Bruce Payne, Lisa Barbuscia
Continuity mistake: After mowing down all the Immortals during the Sanctuary scene, one Watcher tells another to take their heads because they might be Immortals. You see the Watcher to the left side of the screen and a robed figure to his left about four feet away drawing his sword. Suddenly, that same robed figure is now to the Watcher right side and about two feet away.
Jacob Kell: What you need to understand is that I don't care about the game. I don't care about the rules. I don't even care about these pathetic souls you keep locked away as a barrier to the prize.
Trivia: Dimension films infamously pulled some very deceptive marketing in the trailer for "Highlander: Endgame." Much of the footage seen in the original theatrical trailer is a mixture of clips from the prior films and scenes shot exclusively for the trailer that were never meant to be in the final film. This included the trailer explicitly portraying the film as containing sorcery elements (such as the villain being able to duplicate himself and control objects telepathically) and science fiction elements (including Connor and Duncan jumping through some sort-of mechanical "Stargate"-like portal), despite none of these ideas being present in the finished film.
Answer: It seems some catastrophic event occurs. This movie follows the continuity of the television show. In one episode Joe Dawson tells Duncan MacLeod the last time it happened was when two immortals fought in a temple at the base of a volcano. He tells him this caused the eruption that consumed Pompeii. But, Dawson also specifies that it's only a legend, and can't be confirmed as actually being THE specific reason for Vesuvius's eruption.
