The movies and the television series collide.
"What you need to understand is that I don't care about the game. I don't care about the rules."
— Jacob Kell
The fourth Highlander
film, and the first one to cross over with the television series
An enemy out for revenge from Connor MacLeod's past starts causing trouble, and he must team up with his cousin Duncan to stop him.
This film has the examples of:
- Artistic License - Physics: During the final battle, Kell knocks Duncan's sword out of his hands, sending it tumbling off a catwalk. Duncan leaps over the railing and jumps after it, grabbing it in mid-air.
- An Ass Kicking Christmas: The Watcher who tries to assassinate Duncan is surrounded by Christmas decorations, suggesting this trope to be in effect.
- Best Served Cold: Jacob Kell is peeved at Connor for killing his foster father, a Scottish Priest. Kell bides his time for five centuries before carrying out his vengeance fully.
- Better to Die than Be Killed: In the rough cut of the film, Jin Ke beheads himself during the "Last Supper" scene to deny Kell getting his powers.
- Big Bad: Jacob Kell.
- Cruel Mercy: Jacob Kell's goal is to make Connor MacLeod's life a living hell, killing all those close to him and keeping Connor alive until they are the last two Immortals left.
- Devour The Dragon:
- Idiot Ball: Duncan's wedding flashback. Having previously discovered that his bride-to-be is a latent Immortal, Duncan stabs her through the chest on their wedding night without warning, triggering her immortality. Faith's horrified reaction is (ironically) the most plausible character moment of the entire movie.
- Ironic Echo: When meeting in the graveyard, Kell asks Connor "What's wrong? Don't want to be inside me?" Connor asks him the same question during the final fight.
- Let's Fight Like Gentlemen: After a short discussion about honor, Jin Ke challenges Duncan to a martial arts fight.
- Losing Your Head: Carlos moves his eyes a bit after his head hits the ground.
- My God, What Have I Done?: Duncan quickly realized how stupid he had been after he stabbed Faith to make her Immortal.
- Never Trust a Trailer: The trailer has scenes of Jacob Kell wielding godlike powers, splitting into clones of himself, and freezing a sword in mid-air. These scenes were in fact shot specifically for the trailer.
- New Old Flame: Duncan's ex-wife Faith.
- Number of the Beast: Kell has 666 kills under his belt when he fights Duncan.
- Off with His Head!: As par for the course.
- Really Dead Montage: Connor gets one after he is beheaded.
- Revenge by Proxy: According to Kell, he has been hounding Connor by killing his friends for centuries.
Kell: Look back at the endless travesties of your life, and you'll see me, always there waiting in the shadows. When friends and lovers are wiped from your sight, I'm there. When those you cherish die abruptly and for no reason, I'm there for you.
- Soul Fragment: Duncan beheads Connor, he absorbs his swordsmanship skills and perhaps a bit more judging my the morphing effect during the final fight were his face is briefly seen over top of Duncan's.
- Sudden Sequel Death Syndrome: Both Connor and his adopted daughter Rachel bite the dust.
- Sword Plant: Duncan plants a sword as a memorial on Connor's grave.
- Voodoo Shark: A group of Immortals live in voluntary stasis in the "Sanctuary," which is located in a large cathedral, but they are murdered by Kell. In the original theatrical version, the Sanctuary is referred to as being holy ground, but this annoyed fans of the series since it had been established that Immortals are not allowed to kill one another on holy ground. This rule was even followed by every villain, no matter how evil. So the line was excised from the DVD version. But putting aside the fact that it's in a cathedral, the Sanctuary not being holy ground is just as nonsensical when you stop and wonder why a bunch of Immortals opted to be put into voluntary stasis in a place where they'd be vulnerable. Or why the renegade Watchers would establish the Sanctuary on a place that was not Holy Ground. Their goal was to prevent The Prize from being won, ergo they didn't want the immortals there losing their heads any more than the immortals themselves...
- Woman Scorned: Faith is still pissed about Duncan killing her and making her Immortal, but deep down still cares for him.
- Word Sequel: Because the films had Stopped Numbering Sequels by this point, it is only natural.
