Kerala's cultural festivals have had a significant impact on Malayalam cinema. The annual Thrissur Pooram festival, for example, has been featured in several films, including "Sivaji" (1980) and "Lijo Jose Pellissery" (2017). Similarly, the Onam festival, which celebrates the harvest season, has been depicted in films like "Onam Kodathu" (1966) and "Onam Pookalam" (2017). These films not only showcase the vibrant cultural festivals of Kerala but also highlight their significance in the state's social and cultural fabric.
