The Big Swallow

The Big Swallow AKA A Photographic Contortion is a 1901 British short silent comedy film, directed by James Williamson, featuring a man, irritated by the presence of a photographer, who solves his dilemma by swallowing him and his camera whole. The threeshot trick film is, according to Michael Brooke of BFI Screenonline, one of the most important early British films in that it was one of the first to deliberately exploit the contrast between the eye of the camera and of the audience watching the final film.
