The story
Following on from the first motion picture, made in October 1888 by Louis Le Prince in the United Kingdom, the first showing to a paying audience was by Auguste and Louis Lumière of France, in Paris in 1895 and in London the following year, featuring La sortie des usines Lumière showing workers leaving their factory gates in Lyon. Others in France and Britain soon made films, some in "the factory-gate film" genre, and when Mitchell & Kenyon came together they found themselves ideally placed in the heart of the industrial North of England. People were excited at the opportunity of seeing themselves on film, and there were commercial opportunities for short films featuring as many local people as possible.
