Nos Jours Heureux, aka Those Happy Days, is a 2006 French film set at a holiday camp in rural France.
Here’s the description from the All Movie Guide, written by Mark Deming:
“It’s hard to say if the kids or the counselors need more supervision at the second-rate summer camp in this comedy from France. Vincent (Jean-Paul Rouve) runs “Ces Jours Heureux,” a camp for kids in rural France, and as he gears up for the summer season, he has to round up a new staff of counselors to look after the campers. Vincent ends up with six eccentric twenty-somethings, including self-styled ladies’ man Daniel (Lannick Gautry), Canadian party animal Truman (Guillaume Cyr), potty-mouthed lapsed Catholic Caroline (Josephine de Meaux), pretty but non-ambitious Lisa (Julie Fournier), handsome black guy Joseph (Omar Sy), and Nadine (Marilou Berry), who is made the camp medic by virtue of her status as a medical school drop-out. While the campers have to contend with bad weather, worse food and extended periods of boredom, the supposedly more mature counselors hardly fare much better, and occasionally face visits from the cops over the camp’s various safety violations. Nos Jours Heureux (aka Those Happy Days) was written and directed by the team of Eric Toledano and Olivier Nakache, who previously scored a box office hit with Je Prefere Qu’on Reste Amis.”
