Russian Roulette: Subway games (2006)

Russian Roulette takes you on a journey across Russia and Ukraine, exploring post-soviet underground- systems of Kiev, Kharkov, Minsk, Moscow, Nizhny, Novgorod, and St. Petersburg. The reason why there isn't a cast or a crew list and all the artists' faces are blurred is that this film portrays people breaking the law.

Unfortunately the movie Russian Roulette: Subway games is not yet available on HBO Max.
