Laetitia Casta stars in the film Happiness is for Tomorrow, directed by her mother-in-law. The 45-year-old actress has shared the life of Louis Garrel, the eldest son of Brigitte Sy, since 2015.

Casta: “The human encounter with Brigitte, which took an important place in my life, is decisive. I was deeply touched by what she expressed, by her experience, her story. It took precedence over her being part of my family”
