There are so many (unsubstantiated) rumors about Walt Disney; if you believe all of them he was a racist, anti semetic nazi sympathizer and he’s frozen and waiting to be thawed out somewhere in Sleeping Beauty Castle. I don’t believe those things mostly because I don’t want to.
But was he a hallucinagenic drug user? Were he and his animators all really high when they were making “Alice in Wonderland? Are the 7 Dwarfs their big inside joke about the 7 stages of cocaine addiction? Probably not – but it’s surely the funniest Walt Disney rumor I’ve ever heard.
