The MIssing Reel

This historical film is surrounded with tragedy and mystery. On October 24, 1888, only ten days after being shot on Roundhay Garden Scene, Sarah Whitley, featured actress, and Le Prince's mother-in-law, passed away in Leeds. On September 16, 1890, while about to patent his invention in London and to perform his first official public exhibition in New York, Louis Le Prince, director, mysteriously vanished in a train between Dijon and Paris. In 1902, two years after testifying in the Equity 6928 brief, Alphonse Le Prince, featured actor and elder son of the inventor, was found shot dead in New York.
