Acted in her middle school Library/Literature Club`s production of "`Twas The Night Before Christmas" in her nightgown with her favorite teddy bear in December of 1987.

Her last words were "I love you" spoken to her mother.

She grew very close to director Gary Sherman while filming Poltergeist III (1988), and was very proud of the fact that she performed all her own stuntwork for this movie.

As a gift from the crew, she got to keep the goldfish from Poltergeist (1982).

Performed from age 3 in numerous commercials before her Poltergeist (1982) role, most notably for Mattel and McDonalds. She started modeling in 1979 for Mattel "Tuff Stuff" Number Blocks.

She died while on hiatus from filming Poltergeist III (1988), her final movie, which is dedicated to her memory. She was replaced with a blonde stand-in.

During the filming of Poltergeist III (1988), she suffered flu-like symptoms. The symptoms were a result of congenital intestinal stenosis (blockage), which ultimately claimed her life.

Fellow cast members described Heather as having a calming influence on the set. They also described cast meetings with her: everyone would be quickly leafing through the script, while Heather was sitting calmly. Being able to memorize 60 pages of script an hour, she would have already memorized the entire script.

In real life, she loved to go shopping. But according to her mother Kathy, shopping with Heather was a tremendous effort. The girl had to have everything match, from shoes to earrings. She also loved to make and eat sweets, and was the student-body president at her school. For a pet, she had a St. Bernard. Her home life did not, ironically, include the viewing of certain films...particularly not horror films.

During all the horrors that proceeded while filming Poltergeist (1982), only one scene really scared her: that in which she had to hold onto the headboard, while a wind machine blew toys into the closet behind her. She fell apart; Steven Spielberg stopped everything, put her in his arms, and said that she would not have to do that scene again. (Cinefantasque, July 1988)

Her mother claimed a wrong diagnosis was responsible for her death.

President of her class in the 5th grade.
