The Sheltering Sky (1990, Debra Winger, John Malkovich)

Carlos Wallberg notes "At the opening titles, black and white street scenes in New York City are shown with some buses and a subway, may be around the 1940s. Later the action is in a French colony in northern Africa, may be Algeria; a green tram passes by."
Also seen is an elderly and very dusty bus of indeterminate manufacture.
