The cultural festivals of Kerala, such as Onam and Thrissur Pooram , have also been a source of inspiration for many films. Onam , the harvest festival of Kerala, has been celebrated in many films, often symbolizing the state's rich cultural heritage. For example, the 1977 film Moothedathu Mahakavi , directed by A. B. Raj, features an Onam celebration sequence, showcasing the festival's vibrant colors and traditions.
