Charlie and the Chocolate Factory Easter Egg - Ed Wood Reference

When Wonka and the others are in the elevator touring rooms, right around the time they pass through the doll infirmary, they pass by a room with a bunch of pink sheep. Wonka says "I don't want to talk about it," making a reference to "Ed Wood" another film by Tim Burton that Johnny Depp starred in.

In "Ed Wood" Depp's character was a cross-dresser who had a fondness for pink angora sweaters. Angora is a soft wool that can be taken from either sheep or goats. Subtle, but funny.
