Corrected entry: When Sam and Mearing are on the plane, he tells her that the Autobots have no way of leaving the planet, although he knew that Optimus went to the moon to retrieve Sentinel.

Correction: It was never made clear in the film that Sam was aware of this. He wasn't even around when the idea of the Autobots going to the moon was discussed.

Corrected entry: *Spoiler* At the end where Optimus attacks Megatron after Megatron kills Sentinel Prime, Megatron drops Sentinel's body right next to him. In the next shot after Optimus says "Time to find out" Sentinel Prime's body disappears.

Correction: That's because Megatron didn't kill Sentinel Prime. He merely ripped the top half of his helmet off. Sentinel could've easily moved away from the battle before Optimus killed him.
