Walt Disney was a difficult person to work for as he was a perfectionist. He also provided minimal positive feedback to his employees. I loved the old Disney Channel where there were interviews with Walt's "nine old men". These are some of the greats in animation - Les Clark, Frank Thomas, Ward Kimball, Marc Davis. They would talk about the "sweat box" on Friday's when Walt would review all of the animation that had been completed for the week. Everyone was "sweating" because if Walt did not approve the animation you completed for the week, it would have to be redone. There's the famous story regarding Pinocchio when Walt decided to add red coloring to Jiminy Cricket's face after 25% of the film had been completed. All of the scenes which included Jiminy had to be redone. He drove his brother crazy with last minute changes to the animated films and
Disneyland attractions. He decided to change the Pirates of the Caribbean from a walk through to a boat ride after the construction of the attraction had started. He had all of the "steel" torn down and the attraction was rebuilt.
