Has anyone seen "Les choristes" ("The Chorus" in English)? If you haven't, I suggest you go rent it. The subject matter is in the tradition of "Dead Poet Society" where a teacher in school settings changes students' lives in some profound way. Another film that comes to mind is "Cinema Paradiso" that depicts an older man returning home to bury the man who changed his life and the school background also reminds that of "Aurevoir les enfants". "Les choristes" is a blend of these themes.
