I thought never to see this rare canal transport movie shot at Conflans Sainte Honorine port, dealing with conflict between wooden and metal barges. It was directed by Marcel Pagliero, who already shot another movie dealing with union trades, "Un homme marche dans la ville". Here, we are still in working class atmosphere, but with less tension than in "Un homme ...". The photography by Roger Hubert ("les Enfants du Paradis", and so many Carné, Gance, ....) is gorgeous in the port of Conflans with the Seine banks. Casting isn't the best from french cinema, but it's ok for me. Yes, a better casting and more tension would have been interesting, but as it is, it's fine (I like the belgium character, rather funny).
