I am watching (on and off) Bravo's "100 Scariest Moments in Film."
They mention The Wizard of Oz, and I can't help but remember the scene that terrified me as a child, and which in fact, as I recall, made me quit watching once or twice.
It wasn't the monkeys, or the Winkies (the Yeo-he-ho soldiers), or the Witch.
It was the poppies.
Why? Because they were described as "posion," and I was terrified of poison.
That is all.
