Correction: The film makes it quite clear that he wears a straight haired wig over his naturally curly hair, as the National Guard regulations don't allow his length of natural hair. This wig then comes off after he is shot by Slade.
Corrected entry: When the office worker loses his grip on a girder, he falls through a pane of glass below. Just seconds earlier, two women fell from about the same spot, yet the glass was not broken and there is no sign of their bodies.
Correction: Actually you can see the two women's bodies who fell before the guy did.
Corrected entry: During the earthquake, a man reaches out of the window to try to rescue the two window cleaners, who are clinging to the rig. They fall to their deaths. In reality, these guys would have been wearing safety harnesses that secured them to the rig.
Correction: "Should" have been wearing safety harnesses. Many workers disobey safety protocols, like these two guys.
Corrected entry: Early in the movie, a woman walks up to the elevator and presses a button, thereby letting all the people who had been standing there doing nothing into the elevator, but she doesn't get in herself. Why didn't that big group of people just press the button themselves?
Correction: When you have a large group of people standing at the doors to an elevator it is a frequent occurrence that everyone assumes someone else has pressed the button until someone notices that this is not the case. Almost everyone has experienced this.
