Deaths in Film[]

Gerry (2002) [Gerry]: Strangled by Matt Damon, as a mercy killing after they've been lost in the desert for days (just before Matt finds the highway and discovers they both could have been rescued). (Thanks to Eli and Sheena)
The Assassination of Jesse James by the Coward Robert Ford (2007) [Robert Ford]: Shot to death (off-camera) by Michael Copeman in a bar; the movie ends with Michael pointing his gun at Casey, after the narration has already described the details of Casey's death. (Thanks to Steve)
The Killer Inside Me (2010) [Lou Ford]: Shot repeatedly by police after he stabs Jessica Alba; before dying, he ignites the fuel he had poured around the house, burning it down around him. See Stacy Keach in the original 1976 fim.
Ain't Them Bodies Saints (2013) [Bob Muldoon]: Mortally wounded in a fight with bounty hunters or cops, he dies while Rooney Mara kneels by his side.
Out of the Furnace (2013) [Rodney Baze Jr.]: Shot at point blank range in the head by Woody Harrelson.
Interstellar (2014) [Tom Cooper]: Likely dies (off-screen) in the over eighty years between Matthew McConaughey's leaving and return time; we see the older version of his sister (Ellen Burstyn), but not him, so it's entirely possible.
A Ghost Story (2017) [C]: Dies in a car accident (off screen); we see his body directly after the accident and in the morgue when Rooney Mara visits the morgue. He spends the rest of the film as a ghost, with his morgue sheet covering his body.
