Watch Under Ground (1968) : Full Movie Online Free A film study of a Montréal metro station, not as a link in the transportation system, but as a subject for the camera--a place of echoing tunnels, long perspectives, speeding trains, larger-than-life advertisements. The camera sweeps everywhere, wherever there is a scene of intrinsic interest, compiling vignettes of the underground between rush hours. Filmed in black and white, printed on color stock.
