Michael Persinger has theorized that seismic activity could cause poltergeist phenomena. Edlund previously worked on the supernatural horror film "Poltergeist" (1982). The following year, he directed the supernatural thriller "Poltergeist", written and produced by Steven Spielberg. The investigators deduce and confirm that the haunting is caused by a poltergeist. Many claimed poltergeist events have proved on investigation to be hoaxes. Like Poltergeist they can generate uncanny sounds. Another classic Hollywood horror film is Tobe Hooper's "Poltergeist" (1982). Her "Poltergeist" co-star Heather O'Rourke was later buried there in 1988. While interviewing Hotate, Perd Hapley compared the curse to the horror film "Poltergeist" (1982). But the new "Poltergeist" is a fun, worthy horror entry. The poltergeist Peeves wanders around the castle causing trouble wherever he can. After her work in "Poltergeist" (1982), O'Rourke secured several television and TV movie roles. During the production of the original "Poltergeist", Spielberg twice accommodated the child actress when frightened. Ms Zsa Zsa Poltergeist (Andy Billups) was the last bass player. There were also reports of ringing bells and poltergeist activity.
