What is a key characteristic of the typical femme fatale in Film Noir?

The typical femme fatale in Film Noir is characterized by her cunning and self-centered nature. This archetype often embodies complexity and allure, manipulating those around her to achieve her own goals, which frequently involve seduction and betrayal. The femme fatale uses her intelligence and sexuality to influence male characters, leading them into dangerous situations or moral decay. Her traits not only add to the narrative tension but also provide a critique of gender roles, showcasing a woman who is independent, assertive, and often unfettered by the expectations placed on women in society. This characteristic is vital to the Film Noir genre, where themes of moral ambiguity and betrayal are central, allowing the femme fatale to serve as a driving force in the storyline.

In contrast, the other options depict characters that do not align with the typical femme fatale's role. A nurturing and selfless personality represents the opposite of the femme fatale’s manipulative nature, while a timid and demure character lacks the assertiveness and cunning that define this archetype. Lastly, a supporting, caregiver role undermines the femme fatale's position as a primary instigator of conflict and intrigue in the narrative.
