Trivia: When the Autobots are driving up to the spaceship as they are about to leave Earth, the music that is playing is a variation of "Arrival to Earth", the music that played when the Autobots first arrived in Transformers.
Suggested correction: This is not wrong but it also played when the Autobots returned. Did you know that the Bumblebee: The Score has been used in Bayformers?
Revealing mistake: When Optimus has his 'rage' on Wacker Drive, you can see that cars that are being flipped not entirely by volition, since some of them (most notably the red BMW before he cuts a Decepticon clean in half) aren't even touched by Optimus or any Decepticons. (02:15:15)
Suggested correction: Actually if you look real closely, then you will see a shot, which resembles that of Bumblebee's.
