Ten Second Film

“When Conner was commissioned to design the poster for the 1965 New York Film Festival he constructed Ten Second Film, which he intended to act as its television commercial and to precede the film programs in the theater. It was a public 'leader' in that it was composed, like the poster, of a series of ten strips of film (each 24 frames long) of count-down leader, seen as fundamental heraldry of motion picture exhibition.” – Anthony Reveaux

One reason the festival gave for rejecting the film was it "went too fast." It travels the right speed: 24 frames per second. 240. Count 'em.
