The curse of The Omen.
In June 1975, just two months prior to filming lead actor Gregory Peck's son shot himself.
Then, while flying to London in September, Peck's plane was struck by lightning.
A few weeks later, executive producer Mace Neufeld was on a plane to Los Angeles that was also struck by lightning.
And after that, producer Harvey Bernhard narrowly escaped being struck by lightning while filming in Rome.
An animal handler who helped with the "crazy baboon" scene in the 1976 film was mauled and killed by a tiger shortly after shooting wrapped.
Special effects artist John Richardson, who helped with the film's infamous decapitation scene, was in a car crash during post-production.
While Richardson survived the Friday the 13th crash, the head-on collision beheaded Richardson's passenger, assistant Liz Moore, in a manner that was eerily similar to the death scene he helped shoot. Richardson reportedly saw a road sign near the accident scene showing the distance to a Dutch town that read: Ommen, 66.6 km.
A plane that was chartered by the film, but switched at the last minute, went down shortly after takeoff, killing everyone on board.
