Generally considered to be among the first motion pictures in modern history (although more an experiment from the Lumière brothers to use their 'invention' of film, it shows a train arriving at a passenger station... and that's it).
One of the first public exhibitions of motion pictures occurred on 28th December 1895 when Auguste Lumière and Louis Lumière (the Lumière Brothers) exhibited a selection of ten of their single-reel films to a paying audience at a Parisian café. Popular legend has it that, when this film was shown, the first-night audience fled the café in terror, fearing being run over by the "approaching" train. This legend has since been identified as promotional embellishment, though there is evidence to suggest that people were astounded at the capabilities of the Lumières' cinématographe.
The screening of this film on December 28, 1895, is one of the earliest known instances of a paying audience coming together to see a film. However, there had already been screenings of other films that year, such as Young Griffo v. Battling Charles Barnett in May and a medley of several shorts in Berlin in November (see Das boxende Känguruh.
