"Board Game" special effects shoot in my parents' garage, in Essex.
If my memory serves correctly, we shot this about four months after the main shoot, which explains why we are wearing winter woolies and anoraks. Andy is capturing a closeup of Richard Merry for the climax of the chess game, where 'Bored Boy' appears momentarily in the "Alice in Wonderland" style chessboard limbo-land. We used our forced perspective chess board as a reflector to create a weird glow and reflection in his eyes.
Note the case of Whitbread Pale Ale at Nigel's feet, frame right, and the chessmen under the ladder, frame left, waiting for their closeups.
