Throughout his life Gance kept returning to "Napoléon", often editing his own footage into shorter versions, adding a soundtrack, sometimes filming new material, and as a result the original 1927 film was lost from view for decades. After various attempts at reconstruction, the dedicated work of the film historian Kevin Brownlow produced a five-hour version of the film, still incomplete but fuller than anyone had seen since the 1920s. This version was presented at the Telluride Film Festival in August 1979, with the frail 89-year-old director in attendance. The occasion brought a belated triumph to Gance's career, and subsequent performances and further restoration made his name known to a worldwide audience.
