Thaniyavarthanam is a Malayalam film directed by Sibi Malayil and written by A. K. Lohithadas. The film was released in 1987 and is considered to be one of the most hard-hitting Malayalam films of all time. The film brings to light the mind-numbing chaos that descends on a family as an effect of people's unflinching belief in superstition and their lack of empathy . It was lauded for its aesthetic handling of a very sensitive topic, which gave way for many films that dared to question the dogma dictated by religious provocations and the exploitation of people's fears and spirituality

The film stars Mammootty and Thilakan in lead roles, who deliver extremely convincing performances . The direction by Sibi Malayil is brilliant and the film addresses problems in Indian society in a very realistic manner One reviewer even called it "easily the finest Indian movie ever made"

Overall, Thaniyavarthanam is a must-watch for anyone who appreciates good cinema and is interested in exploring the complexities of human nature.
