 Work on the film began in 1918, and some scenes were filmed on real battlefields.
 The film's powerful depiction of wartime suffering, and particularly its climactic sequence of the "return of the dead", made it an international success, and confirmed Gance as one of the most important directors in Europe.
Napoléon is a 1927 silent French epic film written, produced, and directed by Abel Gance that tells the story of Napoleon's early years.
 On screen, the title is Napoléon vu par Abel Gance, meaning "Napoleon as seen by Abel Gance".

 Many innovative techniques were used to make the film, including fast cutting, extensive close-ups, a wide variety of hand-held camera shots, location shooting, point of view shots, multiple-camera setups, multiple exposure, superimposition, underwater camera, kaleidoscopic images, film tinting, split screen and mosaic shots, multi-screen projection, and other visual effects.
