Continuity mistake: Carly's shoes appear to mysteriously alternate several times between black stiletto heels and black ballet flats in-between shots during the climactic action sequence. This is most noticeable during the collapsing building sequence as well as the scene in which Carly speaks to Megatron.
Jerry Wang: Who wants some chicken dinner now, bitch? Huh? Looks like someone messed with the wrong Wang today!
Trivia: Early on in the movie, Sam is watching Star Trek with Leonard Nimoy, who also plays Sentinel Prime. Also, Wheelie's comments on the episode are relevant to Sentinel Prime. (Just replace the word Spock with Sentinel Prime).
Question: During the second movie we see many Autobots, Tex Two Idiot Robotwins and some Motorcyclebots. But now it are only nine Autobots again in the movie. Where did the other Autobots went? Did they got killed or went in hiding?
Answer: No, Sentinel killed both of them in the comics.
Answer: Mudflap and Skids (the two idiot robots I believe you are talking about) were removed from the film due to negative fan reaction. While we don't hear what happened to them in the context of the plot, no reason not to assume they were killed in fighting between the movies. Arcee and Chromia (2 of the motocycles) were killed in the last film.
