Kerala culture has had a profound impact on the development of Malayalam cinema. The state's unique cultural traditions, such as its matrilineal system, have been reflected in many films. The matrilineal system, which was prevalent in Kerala until the 20th century, allowed women to inherit property and played a significant role in shaping the state's social dynamics. Films like Theekkathu (1963) and Agniputhri (1967) explored the complexities of the matrilineal system, highlighting its impact on Kerala's social fabric.
