Continuity mistake: The location of the FireBrand tower keeps changing throughout the film. 1:30 - the tower is in Lower Manhattan, south of the World Trade Center 2:55 - As Kevin Spacey lands, the tower has moved closer to the World Trade Center (side note - the shot immediately before this showed him falling towards midtown Manhattan, not the tower) 3:45 - the tower has moved further north towards midtown 4:50 - the tower appears to have moved back to the position it was in at 1:30. 5:25 - the tower has moved back to it's position at 3:45. 53:25 - We are given a view of the tower from their Central Park penthouse, and it has apparently moved much closer to Central Park (right next to One57 on the other side of Manhattan island) 56:45 - the tower has moved back down to its position at 3:45 and 5:25. 1:17:38 - I'm not entirely sure about this one, but you can briefly make out the two pools of the World Trade Center memorial, which would put the tower at its location at 2:55. 1:18:00 - the tower has moved to the exact location of One World Trade Center (therefore making that building disappear). 1:18:05 - the tower has moved back to its position at 2:55 (now One World Trade is visible).
Continuity mistake: When David and Tom, as Mr. Fuzzypants are free falling from the building roof, David and Tom are falling with the building facing behind them. They turn around to face each other and are now shown with their side facing the building, but when David deploys the parachute, he is suddenly back with the building facing behind him again. (01:17:55)
Continuity mistake: When the cat is attempting to get the fruity pebbles, Jennifer Garner starts to open a drawer. She never fully opens it. In the next shot it is fully open.
Continuity mistake: When David is explaining to Ian about the rival company being taller, he draws an antenna onto the window with a marker pen to explain how it is taller. When David looks at the window with the marker pen drawing of the antenna later in the movie, it is a different shape than before. (00:07:45 - 00:31:40)
Continuity mistake: When Tom, as Mr. Fuzzypants, is spelling out his name in wool, the ball of wool is positioned in front of the name, in the center. About 30 seconds when he runs to pee in Madison's bag, the ball of wool is placed at the edge of the name. (00:36:00)
Continuity mistake: When Rebecca is reading on her iPad and Tom, as Mr. Fuzzypants, reading the newspaper, there is a bowl of strawberries and blueberries on the table, positioned about a foot away from the newspaper. In the next shot, the bowl of strawberries and blueberries is suddenly much closer to the newspaper. (00:54:45)
