Leland Orser

Film Deaths

Alien: Resurrection (1997) [Larry Purvis]: Killed when an alien bursts out of his chest, while he's holding J.E. Freeman in front of his body. Leland is then shot repeatedly by Ron Perlman in an attempt to destroy the alien; it's unclear whether or not he was already dead when Ron fires on him. (Thanks to Wen)
Invader (1997) [Michael Perkett, NASA]: Killed in a nuclear blast in order to destroy the aliens (my memory is vague but It’s confirmed/clarified everyone dies at the end).
The Bone Collector (1999) [Richard Thompson/Marcus Andrews]: Shot repeatedly in the back by Angelina Jolie just as Leland is about to kill Denzel Washington (after having his hand crushed and neck ripped open by Denzel).
Dead Badge (1999) [Pellman]: Killed by Brian Wimmer (my memory is vague but I recall he died).

My Brother's Keeper (2002) [Travis]: Killed by Corin Nemec (my memory is vague but I recall he died).

Confidence (Confidence: After Dark) (2003) [Lionel Dolby]: Killed off-screen by Dustin Hoffman’s assassins, we only learn of his death (notably his body being pulled from the harbour) during a conversation between the main characters (Edward Burns, Paul Giamatti and Brian Van Holt).

The X Files: Firewalker (1994) [Jason Ludwig]: Shot in the back with a flare-gun by Bradley Whitford (as David Duchovny looks on in shock) who then sets his body on fire in order to kill the fungal parasite inhabiting him.

Star Trek: Voyager: Revulsion (1997) [Dejaren]: Playing a hologram, he is destroyed when Roxann Dawson short-circuits him with an exposed power conduit. (Thanks to Neil)
