Continuity: In addition, to the repeated move, a black pawn suddenly moves backward one space, which is not only a continuity error but an impossible move. Without this change, Gibson would not have gotten checkmate as the black queen would have not have been blocked.

Continuity: A move is repeated in the opening chess game. The first overhead shot shows Gibson's white rook near the top left of the board. The adult opponent then takes it with his king at the bottom of the board. Gibson next moves the white rook to the bottom of the board and the adult captures it again, repeating his earlier move.

Continuity: When we see the Russian guy get shot and he falls out of his chair, he knocks the chessboard off the table. But when Jeffrey Spender shows his team the tape, the guy hits the board so that it spins around, instead of falling off completely. (Time)
