Oliyampukal (transl. The Hidden Arrows) is a 1990 Indian Malayalam-language political action film, directed by T. Hariharan, written by Dennis Joseph, and produced by K. G. Rajagopal. The film stars Mammootty, Rekha, Thilakan and Kaviyoor Ponnamma. This film did average business and was dubbed into Telugu as Prathinidhi. The film had musical score by M S Viswanathan. It was a film directed by Hariharan without M. T. Vasudevan Nair as scenarist, soon after several films of the duo including the ever successful Oru Vadakkan Veeragadha (1989). This film also marked Aishwarya’s Malayalam debut (the daughter of notable South cinema female superstar, Lakshmi).
