Director Sathyan Anthikkad has been accused of stealing the story of his latest film Katha Thudarunnu. Novelist and journalist Hamsa Alunkal has come up with an allegation that the story of the film is a straight lift from his novel Mazha Thorathe. The novel tells the story of a woman who is left alone after the death of her husband. Hamsa says that though he had brought the fact to the producers notice, no action was taken. Sathyan has not yet reacted to the allegation.
