Mathilde Warnier is best known for her role in the Amazon Prime Original Series, The Widow, but she also had a cameo on Netflix's soap series, Dynasty as Juliette Carrington. In her own words, her character in The Serpent, Nadine, is "a young, quirky, brave, and bored-by-life French girl . . . [who] befriended her seemingly lovely neighbours, Charles Sohbraj and Marie-Andrée."
