The Choice (1976)

Jean-Pierre, a twenty-three-year-old Belgian theater actor, is engaged to a charming seamstress, Anne Jacquemin, who dreams of nothing else but a quiet married life with children. Belonging to a Brussels company, Jean-Pierre wants to experience more and decides to join a stock company that performs in the South of France. There he meets Juliette Allard, a young dancer who is the lookalike of Anne. As beautiful as her, she is more mysterious and fascinating than Anne. Jean-Pierre loves both: will he be able to choose between these two equally appealing women?
