Trivia: When the planes bombard the desert ruins, the explosion, which holds the Guinness record, took 8 months to be made, more than principal filming took!

Trivia: When Optimus Prime is being rebuilt/upgraded using parts from Jetfire, you can see a brief glimpse of R2D2 coming off of Jetfire (only visible for about 1 second, thus slow-mode should be used to see it, and it is permitted to use slow motion for trivia). (02:17:45)
