In The Five Obstructions iconoclastic director Lars Von Trier (Breaking the Waves, Dogville) dares legendary Renaissance man and director, producer, novelist, poet and television commentator Jorden Leth to remake his seminal 1967 short documentary The Perfect Human, a cocktail-chic, tongue-in-cheek meditation on human behaviour that Von Trier greatly admires.

It's a challenge with a difference, for Leth has to re-produce the film five times, each under fiendish conditions imposed by the perversely playful - and frequently downright sadistic - Von Trier. Leth stoically rises to the challenge; bravely soldiering on through having to render his work into cartoon form, shoot it in Cuba, again in India, and under other increasingly arduous limitations.

A fascinating, visually stunning look at the human condition, and the creativity it engenders, The Five Obstructions is a wickedly enjoyable duel between two great Danes.
