Film Deaths
Final Destination 2''' (2003) [Clear Rivers]: Killed in an explosion when she opens the door to T.C. Carson's hospital room and knocks an electrical cord from its socket, causing a spark that ignites the oxygen leaking from his respirator. (Putting aside the fact that oxygen is an accelerant rather than an explosive...) (Thanks to Germboygel)
Return to House on Haunted Hill (2007) [Sara Wolfe]: Although Ali does not actually appear in this film, it's revealed that her character from 1999's House on Haunted Hill was killed (off-screen) by Erik Palladino between the two movies, staging it to look like suicide. (The part of her ghost is played by Stilyana Mitkova, taking over the role.) (Thanks to Liz)
Obsessed (2009) [Lisa Sheridan]: Crushed to death by a falling chandelier after falling onto a glass table at the end of a struggle with Beyonce Knowles. (Thanks to Tommy, Gerardo, and William)
