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: At breakfast in the BFG cave the bottle of frobscottle is taken from the table by the big bad giant when he says "I is taking this", only to show up again when Sophie clambers out the shnozcumber.
Continuity mistake: When Max runs in the bathroom to complain about Duke, the bathroom door opens into the bathroom against the tub, but when she pushes Max out of the bathroom the door suddenly is on the other side of the door frame opening outwards into the living room. (00:12:20)
Continuity mistake: When time freezes, we see the Hatter's family freeze in the ant farm. When time is mended, he holds the farm close, and his family should have unfrozen at the top of the sand, but they aren't there.
Suggested correction: You might have to look closely, but they are there.
Continuity mistake: During dinner at the Goldsteins', the dishes are empty from one shot to another.
Continuity mistake: The sun angle changes several times during the chase sequence when the dragon is on the flatbed truck.
