Corrected entry: When Perceptor and Grapple are shown firing against the Decepticons (just after the part where the Autobots fire missiles at Devastator) an Autobot runs past Perceptor. If you look closely, this Autobot is actually Swoop. How can he be here now if he shows up in Prime's shuttle a few shots later? (00:18:15)
Corrected entry: How do the Constructicons without mouths manage to play the trumpets at Starscream's coronation?
Corrected entry: When Devastater is first seen, his chest plate is lime green. Then in the next scene he is seen, his chestplate is purple. (00:17:30)
Corrected entry: When Optimus Prime removes the Matrix from his chest, there are TWO Matrices in his torso compartment, although the second one isn't illuminated.
Corrected entry: As Prime chases the Decepticons, Blitzwing can be seen holding his gun, but when he jumps out of the way of Prime he isn't holding it anymore. (00:19:40)
Corrected entry: When Prime transforms back to robot mode and starts blasting the Decepticons, no transforming sound effect is heard.
Corrected entry: Scourge's voice changes completely between his first and second lines.
Corrected entry: In the movie, the transformers actually die when they are shot. In the TV series, they would normally be damaged and would later be repaired. However, it seems that only the Decepticon guns can kill, since in the shuttle attack scene near the start the Decepticons kill some Autobots. But, later Blitzwing shoots an Insecticon and the Insecticon does not die. When Autobots do hit the Decepticons (Prime guns down just about every Decepticon there apart from Megatron, and Blaster shoots down a Constructicon with a huge laser cannon) they do not die, some don't even take damage.
Corrected entry: When Kup says "What's that darn fool doing?" you can see Hound with him. The thing is, later Hound is seen coming out of the shuttle that Prime and the others arrived in to help out in the big battle from Moonbase 1.
Corrected entry: Gears is in the credits but isn't in the movie.
Corrected entry: The Decepticons pretty much total Autobot city in every way possible. So why is it later on in the movie there are 2 perfect shuttles in the open that have not been damaged in anyway? I suppose one may have been the one Prime was in but what about the other?
Corrected entry: At the start of the big battle scene, Ultra Magnus tells Blurr that he can help him "alert the others" Hold on. First, Lookout Mountain has been destroyed with a rather big explosion. Second, the shuttle everyone was expecting to land has just blown up and these things called "Decepticons" have left it. Thirdly, Starscream sets a barrage of laser fire on the base before Magnus has told the others what to do. The others ought to know that they were under attack.
Corrected entry: When Devastator battles the Dinobots to a standstill, he is stuck or sitting in a hole in a wall. When Prime attacks the Decepticons he drives by the very same hole and Devastator (or any of the Constructicons or even Dinobots for that matter) are nowhere to be seen. (00:19:40)
Corrected entry: On the planet of Junk, when Grimlock says "Me not kisser. Me King." his eyes are drawn way too big.
Corrected entry: At the start of the movie, the announcer says that the autobots are planning an assault to take back Cybertron by stocking up energy by having "hidden" bases on two of Cybertron's moons. Just how hidden are these? Laserbeak knows where they are, and Starscream knows this as well. Regardless of the fact that there was an altered script during filming, this is still a mistake.
