Mamangam, the period drama starring Mammootty, tells the tale of valor of Chaavers of Central Kerala and is touted to be one of the costliest films of the industry.The massive structures that were erected on sprawling land were a big hit. Producer and NRI businessman Venu Kunnapilly says that huge sets were erected at Maradu and Nettoor which involved around 2000 workers, 10 tons of steel, 2000 cubic meters of wood. Apart from this, bamboo, grass, coir and palm leaves were extensively used to give a vintage feel. Also, the shoot of the climax scene that lasted 40 days used 2000 liters of oil daily to light the lamps. He says that the massive structures were one of the biggest in the history of Indian cinema.
