|Zelda Rubinstein (1933 - 2010)|
|Poltergeist III (1988) [Tangina Barrons]: Burned to death by supernatural forces acting through a duplicate of Heather O'Rourke; she appears as a spirit afterwards to save the real Heather. (Thanks to Joshua)
Behind the Mask: The Rise of Leslie Vernon (2006) [Mrs. Collinwood]: Apparently dies of a heart attack after Nathan Basael comes up behind her in the library while she's talking to Kate Lang Johnson; she collapses just after Robert Englund shoots at Nathan. (It's unclear whether she's dead or has just fainted; since she doesn't appear in any later scenes, I'll go ahead and list it as a death scene.)
Southland Tales (2006) [Dr. Katarina Kuntzler]: Killed in an explosion, along with everybody else on the Mega-Zeppelin, when Lou Taylor Pucci fires a rocket launcher at it.
