Totalitarian regimes

How have totalitarian regimes used sport and athleticism in films and iconography to support a "cult of personality"?

Talk about different shots like angles, mise en scene, etc. People or movies to talk about Jesse Owens, Berlin Olympics 1936. Talk about different countries (Nazi Germany, Japan, US, Italy, etc.) that used propaganda during that time through films. Main film maker during that time was Leni Riefenstahl.
