Ok, OP is a fag for not providing evidence, but I think it is a fun little conspiracy theory.

I think the movie is autobiographical. Kubrick was always into the occult stuff, but then when he was given a real taste of it, he was disgusted by what he saw. Child orgies with old men and politicians.

Eyes wide shut production was kept super tight, even actors not being given copies of the script except for what they were doing that day of filming. The outside of the masquerade scene was even a rented Rothschild property. Rothschilds are known for their masquerades. The mask worn by the cheif guy had been worn by Prince Charles and Queen Elizabeth, a subtle mod to the real cheifs.

No one had seen the film until the week of screening. Kubrick died a week later of heart failure.
