The commentator

In 1976 Celebrated Danish Filmmaker Jorgen Leth directed the legendary sports and cycling film, A Sunday in Hell, about the Paris Roubaix cycling race. It defined a genre and helped put the grueling Paris-Roubaix on the global sporting map.
Leth now shares his passion for cycling annually as a commentator for this race for Danish television.

Over 35 years later Director Brendt Barbur landed in France with a 30 person international film crew to create a film as an ode to Leth and his film. Seventeen camera persons turned the lens on the race, the spectators, and the atmosphere.
