|Christopher Reeve (1952 - 2004)
Mr. Dana Reeve
|Somewhere in Time (1980) [Richard Collier]: Dies of starvation in his apartment, after losing the will to live due to being separated from Jane Seymour through time. He appears as a spirit afterwards being reunited with Jane. (Thanks to Olenka and William)
Deathtrap (1982) [Clifford Anderson]: Killed (off-screen) during a struggle with Michael Caine; as I recall, the movie suddenly cuts from a scene of Michael and Christopher fighting to a scene of two different actors 'killing' each other in a stage play based on the storyline.
Saturday Night Live (April 6, 1985) [Guest Host]: Shot to death in a WWII-movie-spoof sketch. (Played for comic effect, obviously.) (Thanks to William)
Bump in the Night (1991) [Lawrence Muller]: Commits suicide by jumping out of a window rather than be arrested. (Thanks to Robert)
Village of the Damned (1995) [Alan Chaffee]: Killed in an explosion when he brings a bomb into the barn/classroom in order to destroy all the alien children (while also struggling to keep them from reading his mind and finding out about the bomb).
Smallville: Sacred (2005) [Dr. Virgil Swann]: Dies (off-screen), shortly before the start of the episode; we are informed of his death when Tom Welling gets the news. (This episode was filmed after Christopher's real-life death.) (Thanks to Alex)
