I recently came a across a term I was unfamiliar with called the 'Wilhelm Scream.'  I found out that it is almost an inside joke for filmmakers.  This sound effect that has been used for over 60 years has been in over 130 movies and shows, many of which you've probably seen.

First listen as the history of the scream is explained.

Now check out a bunch of examples where the scream is used.  How many of these have you actually seen before without realizing it was the same sound effect?
