This one is pretty spooky, even if we don’t believe in curses. The Steven Spielberg horror flick Poltergeist wound up spawning two sequels, and in the six years of filming and release of the films, four main character actors died. Considering all the other bizarre happenings and accidents on set, you’d almost think they had to stop the series out of worry they’d just be left with Craig T. Nelson and Zelda Rubinstein by the fourth one.

It is true that Will Sampson and Julian Beck were getting along in years, but at 53 and 60 respectively, they weren’t that old. They were, however, significantly older than Heather O’Rourke, who died of a heart attack due to sepsis complications from previously undiagnosed Crohn’s disease when she was 12.

Lou Perryman is frequently counted in the list, too, although he’s kinda iffy. On the one hand, he lived until 2009, over two decades after the final movie was released. On the other hand, he was murdered with an ax by a complete stranger, which is not really a death you see outside of a horror movie-related curse. So you can make the call on that one.

Prince’s 2016 death made international headlines, but as reported by People, someone very close to Prince died two months before him but made significantly fewer headlines. Denise Matthews, who was the same age as Prince and performed under the stage name Vanity, was Prince’s ex-girlfriend, musical partner, and muse. She headed Vanity 6, an all-girl rock band Prince put together, and was both the inspiration and the planned lead actress for his film Purple Rain. She didn’t act in it, however, because she and Prince broke up before filming could commence.

In 1994, Vanity suffered a drug overdose that severely damaged her kidneys, something she would suffer through for the rest of her life. Months before her death, she revealed she had a rare, fatal abdominal disease (sclerosis encapsulating peritonitis), which likely took her life. A day after she died, Prince dedicated his performance of “Little Red Corvette” to her, saying, “Her and I used to love each other deeply. … She loved me for the artist I was; I loved her for the artist she was trying to be.” Two months later, he was also dead, at the age of 57. Vanity’s age at death? 57.

In the first week of 1998, ’60s pop singer-turned Republican congressman Sonny Bono and Robert Kennedy’s son Michael both died from crashing into a tree while skiing. In accidents that happened just five days apart, both died of head injuries sustained from the crashes. They were known as avid and excellent skiers, and neither was under the influence of alcohol or drugs, although Kennedy was participating in a “football while skiing” game that sounds pretty bonkers on its own. The Kennedy family has had far more tragic deaths than the average family, so surviving members may want to take extra precautions, like just playing standard football.

There’s been a lot of talk about the supposed “Lee family curse,” and plenty of the coincidences surrounding the supposed curse are pretty weird. According to the LA Times, there were some eerily similar circumstances surrounding Bruce and Brandon Lee’s deaths. Here’s the gist of it. 

Bruce Lee had completed some filming for the movie Game of Death when he died of a brain aneurysm. Five years after he died, the film was cobbled together and released by another director using what little footage was available and just throwing in all sorts of clips to fill the gaps, even footage of Bruce Lee’s actual funeral. (Eesh.) But in one scene, Bruce Lee’s character is at a movie shoot, about to charge at a gang of actors firing bullets at him. In the movie script, one of the actors is an assassin who shoots Bruce’s character with a real bullet instead of a blank.

Twenty years later, Brandon Lee would die in almost exactly the same circumstances. While Brandon was filming The Crow, it was an accident rather than an assassin that fired a real bullet at him in place of a blank. But that’s little consolation to his family and friends.

They might not be celebrities today, but this is too weird not to mention. Thomas Jefferson, John Adams, and James Monroe were all U.S. presidents and founding fathers. Kind of a big deal. They wound up doing some stuff in 1776 that was pretty important. Maybe you heard of it.

What they also have in common is they all died on July 4; Jefferson and Adams even died on the same day in 1826 just a few hours apart. Because these were three of the first five presidents, it could have turned into a pattern. When James Madison was on his deathbed in late June 1836, his doctors offered drugs to keep him alive long enough to expire on the 4th of July, but he refused and died a few days early. If these things happen in threes, he might have spared two future presidents from the curse.

All things considered, this was a pretty chill curse. Everyone involved lived relatively long lives for the time period; no one died young, just on a very special day. There are worse ways to go.

Unfortunately, Ian Curtis isn’t the only person with a dark link to Chris Cornell. Chris Cornell and Chester Bennington were pretty good friends, but these two did something that most friends do not and should not do — they both committed suicide. After Cornell reportedly hanged himself on May 18, 2017, Bennington wrote an emotional open letter to him, saying how much he missed and loved him, and adding, “You have inspired me in many ways you could never have known. Your talent was pure and unrivaled. Your voice was joy and pain, anger and forgiveness, love and heartache all wrapped up into one.” In a heartbreaking turn of events, Bennington took his own life, reportedly also by hanging, on what would have been Cornell’s next birthday (53) on July 20, 2017, according to TMZ. We can only hope that the copycat acts stop here.
