The Kiss in the Tunnel
The Kiss in the Tunnel is a 1899 film British short silent comedy film, produced and directed by George Albert Smith, showing a couple sharing a brief kiss as their train passes through a tunnel, which is said to mark the beginnings of narrative editing.
The film was remade under the same title by Bamforth and Company the same year, although they, according to Michael Brooke of BFI Screenonline, adopted a rather less stylised and noticeably more passionate approach to the brief encounter of the title other imitations include S. Lubins Love in a Railroad Train 1902 and Edwin S. Porters What Happened in the Tunnel 1903.
