The Boxing Kangaroo
The Boxing Kangaroo is an 1896 British short blackandwhite silent documentary film, produced and directed by Birt Acres for exhibition on Robert W. Pauls peep show Kinetoscopes, featuring a young boy boxing with a kangaroo. The film was considered lost until footage from an 1896 Fairground Programme, originally shown in a portable booth at Hull Fair by Midlands photographer George Williams, donated to the National Fairground Archive was identified as being from this film.
