Chapeau Claque (1977)

Synopsis
After his father's top-hat manufacturing company goes bankrupt, the young industrialist in this movie moves into the family's old, abandoned mansion and lives off of his wits and whatever little savings remain. A number of other disaffected and fugitive friends live with him. Extremely averse to work and even more averse to ambition, the young man's existence is described accurately in the film's subtitle: "The Merry Confessions of a Layabout." ~ Clarke Fountain, All Movie Guide
