You can find a video compilation of Wilhelm Screams in various films here:

I was wondering what kind of a scream it was. Thanks =)

Wow, now I know what a Wilhelm scream is...thankyou

Glad to help, and hope you're enjoying the site as much as I am!

Isn't the Wilhelm Scream the most used sound effect or something?  I thought I remember seeing something about it...

i had always thought it was the same scream but was never certain but now i know thanks

Informative and entertaining!

 It is a very common scream.

I wasn't 100% sure which scream it was, but this confirms that my guess was correct. Thanks.

Hahaha, awesome.

Here's a vid with the "other" scream people may have thought to be the Wilhelm.

 Holy snap, that was awesome!

THE greatest sound effect ever!

I've definitely picked up on this same scream being in a lot of things, but I never knew it had a name. Awesome!

I'm pretty sure the Whilhelm Scream is in GTA4 too.
