In the past, traditional nuclear families were often depicted as the norm in cinema. However, with the rise of blended families in modern society, filmmakers have begun to explore the complexities of these family structures. Movies like "The Parent Trap" (1998) and "Cheaper by the Dozen" (2003) showcased traditional family dynamics, while more recent films like "The Incredibles" (2004) and "Marriage Story" (2019) have introduced non-traditional family arrangements.
