Gringalet is a 1946 French comedy film directed by André Berthomieu and starring Charles Vanel, Marguerite Deval and Suzy Carrier.

The production benefited from a strong collaboration between the director and the team, including Vandenberghe’s contribution to the screenplay, which enhanced the comedic elements of the original stage play.

This son, Francis, also known by the nickname "Gringalet," played by Paul Vandenberghe, is a crazy, full-of-life young man, free-spirited and artistic in nature, utterly different from the orderly and established family of Lucien.

As the story unfolds, the movie deals with themes in terms of family dynamics, reconciliation, and personality contrast between the disciplined Philippe and the spontaneous Gringalet.

Gringalet is the classical example of post-war French comedy with its dynamic of modernity and tradition, along with offering commentary on the place of family in a rapidly shifting society.
