For JoBeth Williams, starring in Poltergeist alongside an all-star cast, it was Spielberg who made the horror classic. Her initial response to being offered the role? "Is it horror?" She wasn't a fan of the genre, having been "a nervous Nellie" when it came to frights.
However, after meeting Spielberg and reading the script, she discovered that the film boasted a strong family at its core, as well as several powerful female characters. This included Dr Lesh, played by the incomparable Beatrice Straight, which would be Williams' first movie role.
Filming was an improvisational affair, with the cast cracking jokes and having fun even when cameras were rolling. Craig T Nelson, who starred alongside Williams as her husband, had a stand-up comedy background that proved invaluable during scenes where the couple is smoking pot in bed.
The youngest member of the cast, Heather O'Rourke, just five years old at the time, yet bringing an eerie intuition to the role of Carol Anne. Her co-star recalls: "If I cried, she'd cry too...She was such a trooper."
Filming's most iconic sequence - Diane getting dragged across the bed and up the wall by an invisible force? It took several takes to get right, with the cameraman being strapped to a rotating set that made him feel like he was on a ferris wheel.
Meanwhile, behind the scenes, Spielberg waded into chest-deep water, reassuring Williams: "If you get electrocuted, it'll kill me too." That scene would later prove terrifying for viewers as well - featuring real skeletons surrounding Diane after her dramatic fall into the pool.
One of the most surprising facts about Poltergeist? The special effects team had to use real skeletons in that pivotal scene. Fortunately, no one's electrical system was electrocuted on set, but some did feel uneasy when they witnessed how such scenes were brought to life.
Other memorable moments from the film include a chilling shot of Marty (played by Martin Casella) seeing an inchworm-like creature crawling along his kitchen counter, or a scene in which Williams' character hallucinates clawing off her own face.
This was also an era before the PG-13 rating existed - and some scenes had to be significantly altered due to content deemed too intense for younger audiences. In the end, Poltergeist emerged as a masterpiece that would cement its place as a horror classic.
