Plot synopsis: Zepped is a 1916 propaganda comedy short film about a German Zeppelin attack on London during the First World War. Charlie Chaplin appears in the film, although it is unlikely he himself was involved in the production. Making use of stop-motion animation, Zepped uses possibly previously unknown outtakes of three or four earlier Chaplin films: His New Profession (1914), A Jitney Elopement (1915) and The Tramp (1915), and according to Bonhams, By the Sea (1915). Two copies are known: one was unknowingly purchased by a collector who bought an old film reel tin on eBay for £3.20 (about $5) in September 2009 and found the nitrate film inside. He put it up for auction in June 2011 but the sole bid did not reach the £100,000 ($160,000) reserve price. The second copy was found in a tin of assorted items bought from a secondhand shop in Sheffield in July 2011.
