Chaplin's lost films.
"Her Friend the Bandit" and "A Woman of the Sea" are Chaplin's lost films, as no copy is known to exist. As more and more supposedly "lost" silent films emerge, there is some hope that a copy of Her Friend the Bandit will surface in a private collection somewhere. As late as 1965, five of Chaplin's early comedies for Keystone were considered forever lost. Copies of four of them have surfaced in the intervening decades. "Her Friend the Bandit" is still considered Chaplin’s only 'lost' film as no copy is known to exist.
Reviews.
From the "Lexington Herald" in Lexington, Kentucky (June 7, 1914): "'Her Friend, the Bandit', Keystone. One of the funniest and most hilarious comedies in a decade, with a conglomeration of mirth-provoking scenes."
From "The Oregonian" in Portland, Oregon (June 14, 1914): "The Keystone players will offer 'Her Friend, the Bandit', one of those rough and ready farces that make everybody laugh."
