(1967, Jean Marais, Louis de Funès)

French crime fantasy has an opening scene in Edinburgh, which features an Eastern Scottish Bristol Lodekka:

This airport scene is enlivened by several buses. The lowbridge 'decker appears to be from Western Scottish.
The blue and white coach is a Duple-bodied Bedford VAS, but the black and white coach in Western Scottish livery is probably unidentifiable. In the second shot, the Eastern Scottish coach revealed as the 'decker passes is Alexander Y bodied.
