I was wondering if y'all could enlighten me on something?

It is the All-Powerful...the Ever-Lasting...the Known-Galaxy-Wide...the Ultiamte Scream! But...who screamed it?

Recently when I was watching ROTJ, I heard something that I was sure I had heard before. The Scream.

In ROTJ, it happens when the battle between Jabba and Luke is occuring. A scream is heard. It is heard when people are thrown into the Pit of Carcoon. The same scream can be heard in Lord of the Rings, Indiana Jones, and many other movies as well.

I was wondering if you knew where that scream came from and who screamed it first?

I have been paying attention to this for ages but just recently thought to ask my fellow Star Wars fans. I would love to hear what you have noticed about this and if you have heard it in any other popular movies. And also, who screamed it? I heard that it was from some old western movie when a guy was shot and thrown from his horse...not exactly Star Wars like...

Thanks a ton and may the Force be with y'all!
