There are four shots in this film from the original Highlander(1986). The first is a computer-altered and enhanced shot of Glenfinnin, which was originally the shot of Connor walking away from his village. The second is a shot of the Silvercup sign, pulled from the scene of the Kurgan taking Brenda to the building. And in the rooftop Quickening, two shots of Connor and Heather together are also taken from the original.

As Duncan travels toward his rendezvous with Connor, there is a shot of his vehicle passing Silvercup Studios, the scene of the final battle between Connor and Kurgan in the original Highlander.

The scene of Duncan in the hilltop in Scotland was the last shot filmed and arrived for the editors the day they started making release prints.

In the theatrical version of the film, Methos refers to the Sanctuary as Holy Ground. Many fans were upset that Kell killed Immortals on Holy Ground with no consequences, So all references to the Sanctuary as Holy Ground were deleted from the DVD version of the movie.

In the beginning of the movie, Jacob Kell has 661 kills. At "the last supper" (which can be understood as the metaphore of the Jesus's last supper) he kills five more immortals. That makes him the immortal with 666 kills. Which is the number of the devil.

The original trailer for the film featured Conner MacLeod splitting Jacob Kell in two with his sword and in turn becoming two people. This never happened in the film.

Castle Stalker is seen briefly in the film during Connor's flashback scene. This building was also seen in Monty Python and the Holy Grail.

The main villian in each Highlander movie has a name starting with the letter "K" (in order: Kurgan, Katana, Kane, Kell).

The broadswords used by Connor and Duncan as they spar in the flashback are reproductions of the sword used by Clancy Brown in Highlander (1986).

The original title was Highlander IV: The Immortals (the first drafts worked on by creator Gregory Widen). Later official titles included Highlander: The Search for Connor and Highlander: World Without End.

Originally meant to act as a bridge between "Highlander" (1992) and the spin-off series "Highlander: The Raven" (1998) continuing on TV. These plans started to go awry when "Highlander: The Raven" was canceled, and production delays started occurring due to cast availability problems. Dimension Films, who had taken on the project as a way of invigorating the franchise, soon realized that their plans for the film were not going to meet expectations and scaled back on its release, effectively throwing the movie away

The main bulk of filming took place in Romania, at Miramax's behest. Producers William Panzer and Peter Davis were initially opposed to this move

Not screened for critics prior to release.

Bruce Payne came down with bronchitis during filming, forcing the production to reschedule until such a time when he was well enough to perform, which was about three months later.

The Faith fashion show was filmed in London's Millennium Dome exhibition.

For the scene in the cemetery where they meet following the events at the Sanctuary, Duncan and Connor originally spoke French, because both Paul and Lambert are fluent. However, during post-production it was decided to switch the language over to Scottish Gaelic./td>

Connor MacLeod's "Trophy Room" from the first film was reconstructed in detail here, though the hardwood floor is different. The original set had a radial central floor which supported the weight of MacLeod's old blacksmith's anvil in the middle.
