Transformers, 2007

This is perhaps my favourite use of the Wilhelm Scream - the 2007 movie 'Transformers'.

Rather than simply use the scream in its original form, the sound editors of the movie pitched the scream higher, so it would work with the high-pitched cackling of the robot who has his head kicked into the distance.

As with the vast majority of Wilhelms, this one is also the 4th version of the scream.
