Mullum Malarum (; ) is a 1978 Indian Tamil-language drama film written and directed by Mahendran. Produced by Venu Chettiar and V. Mohan, the film stars Rajinikanth, Sarath Babu, Jayalaxmi and Shoba. It marks Mahendran's directorial debut and is partly based on Uma Chandran's novel of the same name, which was serialised in the Tamil magazine Kalki in 1966. Mullum Malarum tells the story of Kali (Rajinikanth), a winch operator of a cable trolley who dotes on his sister Valli (Shoba) since they were orphaned, and clashes with his boss Kumaran (Sarath Babu).
