Marina Sirtis (1955 - )

Film Deaths:

• Blind Date (Deadly Seduction) (1984) [Hooker]: Dissected (off-screen) with a scalpel by James Daughton, after he ties her to her bed and draws a diagram on her chest to prepare her for "surgery." The scene cuts away with Marina screaming as James pulls out the scalpel. (Nudity alert: Topless) (Thanks to Eric)
• Death Wish 3 (1985) [Maria]: Fatally injured while being raped by a group of thugs; she dies (off-screen) some time afterwards. We learn of her death when her husband (Joe Gonzalez) informs Charles Bronson. (Thanks to PortsGuy)
• Waxwork II: Lost in Time (1992) [Gloria]: Hanged by the supernatural forces in the house; her body is later re-animated by the forces to attack Zach Galligan. (Thanks to Christopher and PortsGuy)
• Star Trek: Generations (1994) [Counselor Deanna Troi]: Killed in an explosion along with Michael Dorn, Whoopi Goldberg, Jonathan Frakes, LeVar Burton, Gates McFadden, Patti Yasutake and the rest of the crew, when Malcolm McDowell fires a missile into the sun; their deaths are undone when Patrick Stewart goes back in time and stops Malcolm. (Thanks to Neil and PortsGuy)
• The Grudge 3 (2009) [Gretchen]: Jaw torn off and eyes gouged out (off-screen) by Aiko Horiuchi's ghost after Aiko emerges from Marina's painting. Her body is shown afterwards when Gil McKinney discovers her. (Thanks to Ryan)
• Finders Keepers (2014) [Janine]: Trips over wire falling down her stairs. Her body is later found in Jaime Pressly's garden with her throat slit.

TV Deaths:

• Star Trek: The Next Generation: Cause and Effect (1992) [Counselor Deanna Troi]: Killed in an explosion (along with everybody else on board) when the Enterprise collides with Kelsey Grammer's ship; due to a time loop, this is repeated several times until Brent Spiner succeeds in preventing the collision. (Thanks to PortsGuy)
• Star Trek: The Next Generation: Man of the People (1992) [Counselor Deanna Troi]: Is briefly clinically dead when Gates McFadden stops her vital signs, to break the connection from a being that was draining Marina's life-force and causing her to age rapidly. (Thanks to PortsGuy)
• Star Trek: The Next Generation: All Good Things Part 1 (1994) [Counselor Deanna Troi]: Is revealed to have died (in unspecified circumstances) at some point between the "present" of the series and the "25 years later" sequences. (Thanks to PortsGuy)
• Gargoyles: Future Tense (1996; animated) [Demona]: Vanished into nothingness after Xanatos (voiced by Jonathan Frakes) electrocutes her. Near the end of the episode, it was revealed to be Puck's (voiced by Brent Spiner) illusion; Demona survives the entire series.
• The Closer: L.A. Woman (2005) [Layla Moktari]: Presumably executed (off-screen) after being deported to her home country; she is still alive at the end of the episode, but the implication of her fate is pretty clear. (Thanks to PortsGuy)
• Annihilation Earth (2009 TV film) [Paxton]: Killed (along with everybody else on Earth) in an explosion after she orders Luke Goss to shut down a supercollider, resulting in the destruction of the entire planet. (Thanks to Stephen)
• Titans: Hank and Dawn (2018) [Marie Granger]: Accidentally run over by a van (along with Elliot Knight) while Marina and her daughter (Minka Kelly) are speaking to Elliot and Alan Ritchson.
• The Last Sharknado: It's About Time (2018 TV)

Video Game Deaths:

• Mass Effect (2007) [Matriarch Benezia] Fatally wounded during her battle with Mark Meer/Jennifer Hale; she remains alive just long enough to shake off Peter Jessop's mental control and say her goodbyes before finally succumbing.
