10 Movie Mysteries That Should NEVER Have Been Answered

Highlander was marketed with the tagline "There can be only one." This is a wonderfully kitsch 1980s fantasy flick that cast a Frenchman as a Scot and a Scot as a Spanish Egyptian and despite any confusion that accents may have caused, the plot was as straight as an arrow - an ancient race of immortals will battle each other for 'The Prize,' the sum of all human knowledge. The only way an immortal can die is, as Sean Connery so eloquently puts it, "If your head comes away from your neck, it's over."

The rest of the movie is cut between multiple time frames as Connery's Ramirez instructs Christophe Lambert's MacLeod on how to prepare for The Kurgan, Clancy Brown's brutal leather-clad psychopathic villain. MacLeod, armed with a 2500 year old katana, severs the Kurgan's neck and lives out his days as a mortal, now armed with enough wisdom and knowledge to save mankind.

Highlander II appears to be a sci-fi script that was repurposed for the sake of a sequel, with the origins of the Immortals confusingly ret-conned into a story of exiled aliens from the planet Zeist. Ramirez and MacLeod are put on trial by Zeist's priests, who sentence them to exile on Earth. Why MacLeod doesn't recognise Ramirez on their meeting in the 16th century is never explained and why Ramirez, born in the year 896 BC on Earth, is now from the same 1500s setting is never even mentioned.

Perhaps the tagline might've read: "There should've been only one."
