Dem Panzerkreuzer Potemkin auf der Spur (2007)

"Tracing Battleship Potemkin" goes on to detail the extensive number of shots long lost from constant authorized and unauthorized re-cuts in the last 80 years, and how many of those shots have been returned. Indeed, the film is all the more powerful and lyrical with a number of key scenes (especially the famed "Odessa steps" sequence) filled out and shaded with emotional nuance.
