O' Rourke died four months before the release of 'Poltergeist III,' and the final film was dedicated to her memory. Strangely, in addition to O' Rourke, three other 'Poltergeist' actors have died between the filming of the first and third film, leading many to believe there is a curse surrounding the trilogy -- a rumor sparked by the fact that the first two movies allegedly used real skeletons as props.

While some crucial scenes had yet to be filmed, 'Dark Blood' director George Sluizer refused to recast the role or use special effects to complete the movie. 20 years later, 'Dark Blood' finally made its premiere at the Miami International Film Festival in May 2013.
