Transformers (2007) Easter Egg - Megatron's reverse insulting speech to Starscream

You need the Italian dubbed version.

Play the DVD on PC

Open Windows sound recorder

Skip to the scene when Starscream meets Megatron at the Hoover dam.
Right before the famous line
"You've failed me yet again, Starscream", Megatron says something else.

At first sounds like Cybertronian, but this speech isn't in the English dub.

Record it with the "Windows sound recorder" (or similar software) and then play it reversed.

You will hear, in perfect italian:

"Maledetto bastardo!"

Which in english translates to:
"D*mned bastard!"
