The Great Armored Car Swindle (1961)

This is easily the best worst film ever - hilariously ludicrous plot - theoretically talented back up director Peter Medak; Peter Reynolds' wicked wig; character Peter de Savory named after an actual person; Dermot Walsh's badger hairstyle;,wickedly underrated Arnold Diamond as anxious diplomat. The best is saved till last: beautiful overviews of Gatwick Airport and its surrounding rural area (Creepy Crawley) preserved for all of us from 1961.
