Transformers Beginnings

Transformers Beginnings is a prequel to the Transformers movie that tells the story of what happened before Optimus Prime and Megatron came to Earth. A pity it's only a semi-animated short film that looks like a cheap cut and paste job - they used the illustrations from the Transformers Movie prequel comic book series - but at least you can still hear the familiar voices of Optimus Prime and some characters from the actual movie. Also Megatron is voiced by Frank Welker, the dude who did the original Megatron voice in the old cartoon series.
