 DATE: At the beginning of the film, Pancho Villa makes a remark  about Charlie Chaplin. This scene takes place sometime between the  end of 1913 and the beginning of 1914. Chaplin made his screen debut  in January 1914. In any case, theres no chance that Pancho Villa  would have known Chaplins films, considering that at that time  (1914) the future star was just only another Keystone employee.
