Continuity mistake: When Buck enters Ivy Gold's apartment, Ivy's roommate holds the door open and moves aside to Buck's right. In the next shot when the door shuts behind him, she's on Buck's left.
Continuity mistake: What time does the rapture take place? It's late at night on Ray's plane, which is over the Atlantic. Hattie's afraid Buck's laptop might wake some of the passengers. And when Ray gets home, it's clear that his wife and son were in bed at the time they vanished. But Chloe is driving in broad daylight at the time of the rapture, and comes upon a chaotic accident scene that has just taken place. Chloe was also onthe phone with her mom apologizing for missing her brother's birthday party that afternoon. Finally, when Ray arrives in O'Haire after turning his plane around, it's daytime. Very inconsistent.
Continuity mistake: Buck films a man speaking during the attack on Israel by the Russians. All around him in the air the Russian planes are exploding and are seen everywhere. Later, when Buck watches the tape again there is only the man talking with no explosions seen behind him.
