One of the fascinating pieces of trivia below is true*, the other is false. Do YOU know which is which?

Willy Wonka and the Chocolate Factory (1971)

1) It is said Roald Dahl was reportedly so angry with the treatment of his book (mainly stemming from the massive rewrite by David Seltzer) that he refused permission for the book’s sequel, “Charlie and the Great Glass Elevator,” to be filmed. Seltzer had an idea for a new sequel, but legal issues meant that it never got off the ground. Reportedly, Dahl was so unhappy that he refused to ever watch the completed film in its entirety. Once, while staying in a hotel, he accidentally tuned into a television airing of the movie, but reportedly changed the channel immediately when he realized what he was watching. However, photographic evidence contradicts this: behind-the-scenes footage on the DVD shows him looking happy while visiting the set, and he even attended the premiere. Julie Dawn Cole, commenting in 2011 on these events, remembers him as being a large, scary man.

2) It has long been rumored that the astonished looks on the faces of the children when they see the Chocolate Room for the first time were the actual responses from the actors, as they hadn’t seen this set before. What they’re really reacting to is seeing Gene Wilder in only his underwear high out of his mind on LSD trying to drown one of the Oompa Loompas in the chocolate river, screaming that he demanded to know their anti-aging secrets. What was especially astonishing to the children was that Gene Wilder was also standing next to them in the scene. This is the sole reason why the actor who played Charlie went insane and was never heard from again.
