Napoleon 1927

https://www.imdb.com/title/tt0018192/
Director / Writer: Abel Gance
A massive six-hour biopic of Napoleon, tracing his career from his schooldays, his flight from Corsica, through the French Revolution and the Terror, culminating in his triumphant invasion of Italy in 1797 (the film stops there because it was intended to be part one of six, but director Abel Gance never raised the money to make the other five).
