Mumu is a French film directed by Joël Séria, released in 2010.
[2] The screenplay, of a largely autobiographical nature, was written by the director from 1993 - a long planned project for Séria who had not directed a full-length film since 1987.
[3] In 1947, Roger Lantier, 11 years old, is expelled, again, from his school - to the despair and anger of his father.
He goes next to a new school where 'Mumu' holds sway, "the meanest teacher in the department".
This meeting is one that will leave its mark on the young student forever.
