Film Deaths

Spider-Man 3 (2007) [Eddie Brock a.k.a. Venom]: Killed in an explosion when he jumps towards the alien symbiote to re-bond with it, just after Tobey Maguire had thrown one of James Franco's pumpkin-bombs at the symbiote. (Thanks to Anton, Andrew, Fortza, Shollum, Hunter, and Dario)
Predators (2010) [Edwin]: Stabbed in the head by one of the predators after first being stabbed in the throat by Adrien Brody who then rigs his body with booby-trapped bombs.
Interstellar (2014) [Getty]: Possibly dies (off-screen) before Matthew McConaughey returns from his space journey; we don't see his character in the future when Matthew comes back through the black hole.
American Ultra (2015) [Adrian Yates]: Executed in the woods with multiple gunshots to the chest by Bill Pullman while Connie Britton watches.
