The first Highlander movie came in 1987, starring Christopher Lambert
as Connor MacLeod, and Sean Connery as Ramirez. A sequel followed, also starring Lambert and Connery, which said
immortals came from another planet--this was later remastered, with the
director's cut, Highlander 2: The Renegade Version. This one had no mention
of the planet Zeist.
The series was next. It starred Adrian Paul as Duncan MacLeod, a clansman of Connor's, 50 years younger. Christoper Lambert appeared in the first episode.
Highlander 3: The Final Dimension came in 1994, again starring Lambert and Connery.
Highlander 4: World Without End starts production this fall. It stars both Christopher Lambert as Connor, and Adrian Paul as Duncan(yay!).
New info: Highlander IV will be taped in Paris, NY, Bucharest, and Scotland!
New rumors: Methos *might* be in it!
