R.S. Madhu is a well-known Mollywood artist. His talent for the arts has shown up in various ways, and he paints portraits, creates sets, directs films and plays, writes scripts, and makes stage. His long career as a teacher had no impact on my love of the arts. Nellimoodu Ramakrishna Pillai, his father, was a well-known theatre personality and activist in Venganoor.  He worked as social studies and English teacher at a local school. He earned the title of the best teacher, and he retired as the headmaster of Venganoor High School. He has directed and scripted several plays, some of which were inspired by the works of Kerala's literary giants. He has done the make-up for several theatrical legends over the years. Many performers continue to demand that he find time to do their theatrical make-up. Calicut University, Kannur University, and CUSAT are among the universities in Kerala where he produced academic robes.

The portraits of Swati Tirunal, John Caldecott, and Godavarma Raja, by him, are in the Senate Hall. Portraits like these are one method to remind future generations about notable men and women and their accomplishments. He continued his education at the College for Fine Arts after graduation. It was the School of Arts that developed his skills in drawing and painting. ManojKumar and VinodKumar, his kids, are also talented artists. A few years ago, he won the National and State honors for a documentary on the renowned reformer Ayyankali from his hometown. He had already painted Ayyankali's portrait. That portrait was used to create his statue at Vellayambalam. Now he's working on a documentary about G. Chandrasekhara Pillai, a Venganoor-born veteran politician. He also made documentaries on Saint Kuriakose Elias Chavara and Chattambi Swami.
