Olympia is a 1938 Nazi German sports film written, directed and produced by Leni Riefenstahl, which documented the 1936 Summer Olympics, held in the Olympic Stadium in Berlin, Germany.
P.s. This is a shortened version of the two parts of the film. I've cut out the competitions as those aren't really interesting and left the beginnings and ending of both films - the most artistic parts.
Three versions of the film, all on the Internet Archive website : https://archive.org/details/OlympiaColorized
