Love turns out to be all in the family in this romantic comedy from France. When an elderly couple decides to marry, their families come together for a wedding banquet that turns into a raucous, wine-soaked celebration. Marthe (Marie-Christine Barrault) and Ludovic (Victor Lanoux) are distant cousins related by marriage who meet for the first time at the reception; they take an immediate liking to each other and resolve that they should see each other more often. Before long, they've become close friends, but their spouses begin to think there's more going on than just good conversation. However, the more people are convinced the two have become lovers, the more the idea of taking their friendship to the next level appeals to them. Marie-France Pisier has a memorably funny "suicide" scene as Ludovic's wife. Cousin Cousine was a surprise commercial success in the United States, where it received several Academy Award nominations and spawned an Americanized remake, Cousins (1989).
