This may be the first post-apocalypse film in which the apocalypse isn’t cataclysmic, at least not in the nuclear holocaust/return of Christ sense. Although it does in fact begin immediately post-apocalypse, for some time it is not clear that there was in fact an apocalypse at all. This key question persists for the entire film; was there an apocalypse, and if so what was it? Here our protagonist (Bruno Lawrence) simply wakes up in the morning to find a world devoid of people. All of them have simply vanished at the same time, in the middle of whatever it was they were doing at that instant; flying aircraft, driving, crapping, making coffee. He proceeds to go very nearly ape-shit.
