Highlander: The Source is a 2007 American science fantasy action adventure film, and the fifth installment of the Highlander film series. Directed by Brett Leonard, this and the prior installment, Endgame (2000), follow the continuity of Highlander: The Series (1992–1998), continuing the story of immortal swordsman Duncan MacLeod, with actor Adrian Paul reprising his role from the series and Endgame. It is the only Highlander film not to feature the original protagonist, Connor MacLeod. Taking place in a future version of Earth that is largely violent and chaotic, the story depicts Duncan and allies seeking out an energy well that may be the "Source of Immortality".

Highlander: Endgame is a 2000 American fantasy action film directed by Doug Aarniokoski and starring Adrian Paul, Christopher Lambert, Bruce Payne, and Lisa Barbuscia. It is the fourth theatrical release in the Highlander film series and it serves as a continuation of both the Highlander film from 1986 and the Highlander television series. The film reunites Duncan MacLeod, the lead character of the series, and Connor MacLeod, the lead character of the films. In the film, the Macleods need to deal against a new enemy named Jacob Kell, a powerful immortal who is willing to break any rule to win the Prize. This marks Lambert's fifth and final appearance as Connor. Highlander: Endgame was released on September 1, 2000. A stand-alone sequel, Highlander: The Source was released seven years later, with Paul reprising his role.
