This paper explains Hollywood's persistent gender-based pay gap, emphasising the systematic undervaluation of female actresses despite having status and experience equivalent to their male counterparts. The study interrogates how social stereotypes and the historical dominance of patriarchal culture in the industry have solidified disparities in earnings. The writing explains that gender-based pay inequality remains strong, even when considering role complexity and box office success factors. The discussion results indicate that external perceptions from various researchers and the portrayal of women in media related to career trajectories and earning potential demand a broad change in the Hollywood film industry to achieve gender equality.
