Terry O'Quinn (1952 - )
- Silver Bullet (1985) [Sheriff Joe Haller]: Bludgeoned to death by Everett McGill with a baseball bat after Everett turns into a werewolf while Terry tries to arrest him.
- The Stepfather (1987) [Jerry Blake]: Shot in the back/chest/shoulder by Shelley Hack, then stabbed in the chest with a knife by Jill Schoelen. (NOTE: although the sequel states he managed to survive his wounds, it's clear they intended this to be an actual death scene)
- Young Guns (1988) [Alexander McSween]: Killed during a shootout in/at the Battle of Lincoln.
- Pin (1989) [Dr. Frank Linden]: Killed in a car crash along with his wife (Bronwen Mantel) due to either his recklessness or in fault by his life-size anatomically correct medical dummy Pin (it's left to interpretation if Pin somehow caused this accident) (my memory is vague but it’s confirmed/clarified he dies).
- Stepfather II (Stepfather 2: Make Room for Daddy) (1989) [Jerry Blake/Gene F. Clifford]: Stabbed with a hammer claw in the chest by Jonathan Brandis. (NOTE: The 1992 sequel Stepfather 3 revealed that the character, now played by Robert Wightman, had survived his wounds, but it's obvious that this was intended to be a death scene.)
- The X-Files: Fight the Future (1998) [Darius Michaud]: Killed in an explosion after he lets a bomb detonate rather than disarm it.
- American Outlaws (2001) [Rollin H. Parker]: Shot by one of the James brothers (Colin Farrell or Gabriel Macht, I’m not sure which) as he draws a gun.
- Millennium: Goodbye to All That (1999) [Peter Watts]: Shot in the head by unknown Millennium Group member.
- The X-Files: Trust No 1 (2002) [Shadow Man]: Killed by exposure to magnetite.
- Lost: The Life and Death of Jeremy Bentham (2009) [John Locke]: Strangled to death by Michael Emerson, while Terry is talking to him; Michael then arranges it so that it looks like a suicide by hanging. (Terry's corpse has appeared in numerous flashforward sequences prior to this episode, but this episode shows his actual death.)
- Lost: The End (2010) [John Locke/Man in Black]: The "Man in Black" (in the form of "John Locke") falls to his death after being pushed off a cliff at the end of a struggle with Matthew Fox, after first being shot in the back by Evangeline Lilly.
- Castle Rock: Severance (2018) [Dale Lacy]: Commits suicide by tying a rope around a tree then noosing the other end around his neck, then speeds his car off of a bluff into the lake hanging himself in the process.
- Hawaii Five-0: Pio ke kukui, po'ele ka hale (2018) [Joe White]:
