Kiara Advani was the first actor whose look from the film was unveiled. She plays a character named Nadia. In the poster, tears in her eyes hint at pain and inner conflict, setting the tone for a dark fairytale. Kiara has described the role as challenging. After a difficult 2025, with Game Changer and War 2 failing to perform at the box office, the actor is reportedly placing strong hopes on Toxic to mark a turnaround.
