Brent Spiner (1949 - )
- Star Trek Generations (1994) [Lt. Commander Data]: Killed along with the rest of the Enterprise crew when the planet they had crash-landed on is destroyed by a shockwave caused when Malcolm McDowell fires a missile into the sun: their death are undone when Patrick Stewart goes back in time and stops Malcolm.
- Independence Day (1996) [Dr. Brackish Okun]: "Killed" (or at least clinically) when the alien he's operating on attacks and strangles him by the throat with its tentacle, subsequently taking over his body to communicate; Robert Loggia, Adam Baldwin and Bobby Hosea kill the extraterrestrial. (according to Spiner, a scene where Baldwin checks his pulse and says "He's dead, sir" was filmed but then cut out of the movie; the director's commentary notes he was just knocked out and in a coma, and sequel Independence Day: Resurgence proves that by showing Spiner remains in a 20-year coma; but this is still listed since this was originally intended as a death scene.)
- South Park: Bigger Longer & Uncut (1999; animated) [Conan O'Brien]: Commits suicide by jumping through the window of the studio landing on a car below. (Played for comic effect.)
- Star Trek Nemesis (2002) [Lt.

Commander Data / Lore / Dr. Noonian Soong]: Playing a triple role as the android "Data", his evil twin "Lore", and their human creator, "Dr. Noonian Soong", "Dr. Soong" is fatally injured when "Lore" tosses him against a table with equipment (though he was already dying of old age/natural causes); he dies shortly afterwards while talking to "Data".
- Star Trek: The Next Generation: Cause and Effect (1992) [Lt. Commander Data]: Killed in an explosion, along with the rest of the crew, when the Enterprise collides with Kelsey Grammer's ship; due to a time-loop, this is repeated several times until Brent succeeds in preventing the collision.

- Star Trek: Picard (2020) [B-4, Lt. Commander Data, Dr. Altan Soong]: Playing a triple role. "B-4" dies off-screen between Star Trek Nemesis and the present day, as his primitive positronic network was unable to support Data's neural network anbd collapsed. His remains are kept disassembled at the Daystrom Institute, and are shown to Patrick Stewart by Alison Pill. "Data" is revealed to have been resurrected by "Altan" and John Ales, and is living in a simulated reality. He dies again when Patrick shuts down the simulacrum at "Data's" request. "Altan" survives the first season (B-4's remains are props and not actually portrayed by Spiner. However because the role was originated by Spiner in Star Trek Nemesis it is listed here to record his death between the film and series).
