Cultural depictions

"Kolathiri" appears as a character in a Malayalam film titled Urumi. The film was loosely based on Portuguese interference in north Kerala and the misdeeds committed by Vasco da Gama, who was hailed as a hero in the west but was actually a cold-hearted tyrant to other lands of the spice route; his entry into Kerala politics and manipulating the kingpins and a young Indian who tries to kill Vasco da Gama. The movie was released on 31 March 2011.
