Dabney Coleman

Film Deaths:

9 to 5 (1980) [Franklin Hart]: Killed in three fantasy segments; when he is shot and his head mounted by Jane Fonda, when he is tied up and suspended over a campfire by Dolly Parton, and when he is poisoned and ejected out of a window by Lily Tomlin.
Domino (2005) [Drake Bishop] Shot to death by Stanley Kamel along with Peter Jacobson at top of Dabney's hotel because Stanley thought Dabney was responsible for the death of his son. (His son was in fact still alive.)

The Outer Limits: The Mice (1964) [Dr. Williams]: Fatally beaten (off-screen) by the alien Chromomite (Hugh Langtry); he dies after collapsing in front of a guard.
The Outer Limits: Specimen: Unknown (1964) [Lt. Rupert Howard]: Poisoned by one of the space flowers when it sprays a mist into his face; he dies after getting rid of it (but before he can get rid of the others).
The Invaders: The Saucer (1967) [John Carter]: Disintegrated, along with Kelly Thordsen and Robert Knapp when their car goes off the road whilst pursuing some aliens and the leader, Sandy Kenyon, fires his ray gun at the stationary car. (Thanks to Brian).
