Stills from Maurice Lemaitre’s Le Film Est Deja Commencé? (1951). Image from Vertigo (see below).Lettrism (or Lettrisme or Letterism) is a French film and visual poetry movement that enjoyed a brief heyday as the avant-garde du jour in 1950s Paris, and is often associated with the French Revolutionary Student Movement of 1968. Founded by Elvis lookalike Isidore Isou (born Ioan-Isidor Goldstein, 1925-2007), Lettrism influenced other forms of art and poetry in Europe and Latin America up to the present and likely into the future, even as most Viners and Snapchatters remain unaware of this strange fold in the space-time continuum of art.
