However, there are several French films with similar titles or themes related to marriage that were released around that time. Could you please clarify which specific film you're interested in? Knowing the full title, director, or even a brief plot summary would help identify the cast.
For example, you might be thinking of:
* "Le Mariage de Figaro" (The Marriage of Figaro), a 1984 film based on the famous opera by Mozart.
* "Le Mariage de Louis XIV" (The Marriage of Louis XIV), a 1984 historical drama about the marriage of the French King.
* "Notre Amour" (Our Love), a 1984 French film about a troubled marriage.
Once you provide more details, I can help you find the cast information for the specific film.
