This isn't film bashing, i LOVE the movie. I just thought it'd be a good idea to have all of these things that are presently being discussed across a billion threads all brought into one... so here's what i've noticed, and every time soneone points out another one I'll add it to this list. and yes, some of these were from imdb. SOME. -Barricade and Scorponok disappear without explanation. -Ironhide's slow motion missile dodging/assault is clipped in two for some reason. -The amount of donuts remaining on Glen's plate during interrogation changes many times. -When the Air Force Soldiers are on the V-22, Epps is wearing a pair of Oakley Monster Dog sunglasses on his head for the first minute or so. When it flashes back to him during conversation, they are gone. -When Sam arrives at the party, the camera crane can be briefly seen as a shadow. -Sam and Mikaela are standing with Bumblebee after his legs get blown off, then it cuts to Sam running away, then it cuts back to Sam sitting in front of Bumblebee saying "I'm not gonna leave you." -When Sam and Mikaela are in the '74 Camaro, there are insert shots of the odometer and gages/dashboard which are actually from the new Camaro. Also, the windows change between tinted and untinted. -During the first ride that Mikaela takes in Sam's car, both windows are obviously down during their conversation. Yet, neither one has any wind blowing on them. Their hair never moves. -When Mikaela walks away after trying to fix Sam's engine, the passenger door is open while he is tying to start the car. When the car starts and he gets out to slam the hood, the passenger door is suddenly closed. -In the beginning, during the Qatar scenes, you can see mountains in the background. The country of Qatar has no mountains and the highest elevation is 295 feet above sea level. -After Sam is chased by the dogs, and his car is circling him, he yells "Take the stupid keys", but his mouth is not in sync; possibly saying something else. -When in the air, Air Force One is a 747. On the ground, however, it is suddenly a KC-135 painted to look like Air Force One. You can see the refueling boom when Barricade pulls up. -The final battle takes place in the fictional "Mission City", but clear shots of the easily recognizable LA skyline are shown throughout. -When they go to the lake party a cameraman is visible in Mikaela's boyfriend's truck's mirror. -When the Pentagon sends a Predator drone to provide footage of the Rangers' battle with Scorponok, it is actually an RQ4 Global Hawk. Predators have propellers, not jet engines. -When Bonecrusher tackles Optimus Prime, they are at ground level on a multi-lane freeway, yet they go flying off a two lane bridge/causeway. -After all landlines and cell phones are to be shutdown, people in the background of the fight scene in the city are seen using their cellphones. -Mikaela's nail polish appears and disappears. -The taxi Maggie flags to take her to Glen's is different from the one she arrives in.
