The cynical might suspect that this is just another step in the very meta marketing campaign for the film (which, judging by early reviews, features a scene in which its star Adam Driver appears to interact with a member of the audience; good luck with ensuring that happens at every screening for the week or two Megalopolis lasts in cinemas). 

But it nevertheless places the picture in a tradition of previews that, for whatever reason, are often more memorable than the films they tease. From trailers that give away the entire plot, including the final act twist, to ones that refuse to show a single frame of footage from the picture, here are 10 of the most unusual ways of marketing a film in history: some successful, some decidedly not. 

1. Psycho (1960)

Judged by the fast-cutting montage technique that audiences expect these days, trailers for many films pre-1980 now seem almost laughably quaint, a series of random images and clips slung together without coherence and with intertitles and voiceover making grandiose promises about the picture’s credentials. Unsurprisingly, Alfred Hitchcock did things differently. He was that rare director who was as famous, if not more so, than the stars in his pictures, and he often positioned himself front and centre of the trailers for his films.
