Transformers: Dark of the Moon2011

Optimus Prime:
We were once a peaceful race of intelligent mechanical beings. But then came the war, between the Autobots who fought for freedom, and the Decepticons who dreamt of tyranny. Over matched and outnumbered, our defeat was all but certain. But in the wars final days, one Autobot ship escaped the battle. It was carrying a secret cargo, which would have changed our planets fate. A desperate mission. Our final hope. A hope, that vanished.
