Das Boot: Behind The Scenes (1981)

Directed by Wilhelm Bittorf

Comprehensive classic piece that looks at the process of creating the movie, told with a strong, well-constructed narrative that plays almost as a movie itself, a detailed retelling of how the movie was made and the dedication to authenticity that's evident right down to the finest little details on the ship. After a narrator sets the scene for various segments from the film, the piece takes its time to take a closer look at all of the elements that are necessary to create the movie and the challenges of shooting such a labor- and authenticity-intensive picture.
