scared by performing a particular stunt, Spielberg replaced O'Rourke with a stunt double wearing a blonde wig, and when disturbed by the portrayal of child abuse, Spielberg did not require her to perform the take again. For her work on the film, O'Rourke earned between $35,000 and $100,000. Poltergeist would go on to receive a cult following and critical acclaim, garnering three Academy Award nominations and a Young Artist Award nomination for O'Rourke. She was lauded for her performance, with The New York Times noting that she played a key role, writing that "With her wide eyes, long blonde hair and soft voice, she was so striking that the sequel played off her presence." Her delivery of the lines "They're here!" in the first film, and "They're baa-aack!" in the second (that film's tagline), placed her in the collective pop culture consciousness of the United States. "They're here!" is ranked No. 69 on the American Film Institute's list of 100 Movie Quotes, and PopSugar included the line on their list of "100 Greatest Movie Quotes".

Poltergeist III was her final feature, released in June 1988, four months after her death. Illness and death In early 1987, O'Rourke became ill with giardiasis, which she contracted from well water at her family's home in Big Bear Lake. She was subsequently diagnosed as having Crohn's disease. She was prescribed cortisone injections to treat the disease during the time she was filming Poltergeist III. The steroidal injections resulted in facial swelling of the cheeks, which O'Rourke's mother said she was very self-conscious about. On January 31, 1988, O'Rourke began exhibiting
