 FAKE: As Unicron is about to devour the first planet at the start of  the film, theres a shot of a robot looking up towards him saying  "its Unicron!", at this part theres an animation error. If you  look carefully the bottom part of Unicrons outer ring overlaps an  object that is in the foreground, this would mean that Unicron is  actually smaller than the objects on the surface of the planet and  not bigger than the planet overall as established by the next few  shots.
