Audio problem: Right as Duncan leaps into the "chain room" in the final fight, he lets out a light "Ugh!" sound. Then, about 5-10 seconds later, when Duncan surprises Kell and kicks him... Kell makes the EXACT same "Ugh!" sound effect.
Highlander: Endgame (2000)
1 audio problem - chronological order
Directed by: Douglas Aarniokoski
Starring: Christopher Lambert, Adrian Paul, Bruce Payne, Lisa Barbuscia
Deliberate mistake: In the Director's Cut (the version most readily available on DVD), there is literally an entire 15-second chunk of the final fight that is repeated twice within 60 seconds. (It's the bit where Duncan and Kell are fighting on the ground, Duncan kicks Kell, then Kell kicks and slices Duncan) It's impossible not to notice, and it's not they're flashing back to what just happened... they just repeat the same 15 seconds of footage, add different sound effects, and assume people won't notice.
Connor MacLeod: Life brings hope and pain, but revenge never brings redemption.
Trivia: The character of Manny, one of Kell's posse, is played by Vernon Rieta, who has been Adrian Paul's Hung Gar Kung Fu teacher for years.
Question: In Highlander The Sorcerer, Conner had adopted a son. Anyone know what happened to him as in Endgame, Conner gets killed?
Answer: It's hard to say. Since the series totally ignores "Highlander 2" some assume that they also ignored "Highlander 3." But if you don't like that idea, you can probably assume he's off at college with his own life, or maybe even been killed by Jacob Kell.
