Could go on and on about red wine with fish, the chess match, catches horizontal, gypsy fights, etc. but just looking at the helicopter chase here. That scene and the ensuing boat chase were filmed in the west of Scotland, an area called Argyll and Bute, standing in for the plot location of Turkey. The helicopter chase had to have been influenced by the cropduster scene in Hitchcock's 1959 North By Northwest, though we do get a pilot's eye view here as well and some great scenery. Years ago we went on a hike in this area and found a burned out helicopter... same one?? Maybe crashing is common here...
