- Burnt Offerings (1976) [Ben Rolf] Thrown out of the balcony by the supernatural forces and lands on his car.
- The Brood (1979) [Dr. Hal Raglan]: Beaten to death by Samantha Eggar's "rage children" while Oliver is trying to rescue Cindy Hinds.
- Venom (1982) [Dave Averconnelly]: Bitten on the leg by the black mamba after it crawls up his pants leg. (Thanks to Matt)
- Clash of Loyalties (1983) [Colonel Leachman]: Dies. (This seldom-seen film is very rare, but clips of it, including a scene of Oliver dead in a coffin, appeared in the TV documentary Saddam Goes to Hollywood.)
- The Misfit Brigade (1987) [The General]: Shot to death along with David Carradine by Bruce Davison and the surviving 27th Panzers. The film ends with them making a mock firing squad then opening fire
- The House of Usher (The Fall of the House of Usher) (1988) [Roderick Usher]: Presumably killed, though I don't know the circumstances. (Based on the plot synopsis on the IMDB listing, this adaptation varies drastically from the original story, including eliminating the character of the sister who kills Usher, so I don't know what happens in this version.)
- The Pit and the Pendulum (The Inquisitor) (1991) [Cardinal]: Suffocated after being entombed alive by Lance Henriksen's men.
- Gladiator (2000) [Proximo]: Stabbed to death by Roman soldiers. (This scene was filmed after Oliver's real-life death; it was accomplished by using CGI to superimpose Oliver's face onto a stand-in as the soldiers close in on him. The original script called for Oliver to survive the movie and eulogize Russell Crowe at the end, but his death forced the filmmakers to rewrite his character's fate.) (Thanks to Matt)
- Treasure Island (Devil's Treasure) (1990) [Captain Billy Bones]: Dies of a heart attack from fright, after being given the Black Spot by Christopher Lee. (I haven't seen this version, but I'm familiar with the story.)
- Nephew of Carol Reed (director)
