Plot hole: When Alex and Clear are sitting and having coffee they are on a corner. He looks in the window to see the bus pass, and as he looks to see if it is there, it's not. As the camera pans across the street, there is some construction going on which is blocking that whole road from being used, but then Terry, Carter's girlfriend gets "waxed" by the bus - no way it could have got through all that construction.
Plot hole: With how much vodka was seen leaking out of Ms. Lewton's mug from the crack, it would have already been empty or close to empty when she took a drink next to the computer and she would have noticed this and the crack. (00:59:00)
Plot hole: During the premonition, Carter and Terry are sitting directly next to each other. However, we know that before Carter dies, both Terry and Lewton (who is sitting 2 rows in front of them) have to die first. When Alex sees the report that marks the explosion path, it suggests there is a chain reaction that goes from Tod's seat to Terry's, and then Lewtons. If this is true, should Alex have not died with Tod and Carter with Terry? Tod can actually be seen getting hit in the head with somebodies luggage, and if this is how he died, the news report suggesting a 'chain reaction' is wrong; Tod's seat never explodes. Can anyone tell me if the drawing Alex did with the line going from seat to seat (before the explosion) is not supposed to be an explosion? If you slow down the premonition, both Terry's seat and Lewton's seat blow up about a split-second before the explosion erupts - this is possible but the distance of one of the explosions from Lewton is larger than the explosion from Carter.
Answer: The scene where Terry was killed was most likely shot during the day. It is quite common for film makers to film a scene during the day to get the right lighting effects and then later CGI the night sky and the proper shadowing. This is most effective when you have an area that would otherwise be too dark or have environment that wont allow for the proper lighting for a night shoot. As for the bus, your guess is as good as mine.
