Two naked men wrestling in the mud. It seemed to be some kind of organized competition (there was a judge telling them to start/stop). They were indoors. There were more pairs of people doing the same thing in separate mud pits in the background. In another scene, one of the naked mud-wrestlers, still nude, now clean, talks to his therapist about something.
I saw this on TV around 2009(?), it was broadcasted (dubbed) in Russian, and it was in color.
Note: The guy is clothed at the beginning of both scenes described, but he then undresses and carefully puts his clothes aside.
