 During one of the conversation segments in the documentary  Lars von Trier (qv) and Jørgen Leth (qv) agree that Leth will  receive full credit for the fifth and final Obstruction entitled  "The Perfect Human: Avedøre, Denmark" despite not directing it, and  that Trier will receive none, although he will direct it. This,  apparently, is within the rules of the game played out by the two  directors during the documentary, and serves as an inside joke.
