Horror classic Poltergeist became known as one of Hollywood's most cursed film franchises after the cast suffered a number of tragedies once filming wrapped.

Dominique Dunne, who played Dana Freeling in 1982's Poltergeist, became the victim of a grisly murder the year the film was released, while Lou Perryman, who played Pugsley in the original movie, was hacked to death with an axe at the age of 67 in 1992. And they weren't the only cast members to meet a tragic end.

Child actor Heather O'Rourke played Carol Anne Freeling in Steven Spielberg's 1982 movie Poltergeist, before going on to star in two sequels. Carol became an iconic horror film character, widely recognized for her long platinum blonde hair and for calling out to her mom from the beyond
