Thenmazhai,
Ninaivil Nindraval,
Bommalattam,
Aayiram Poi and
Panam Paththum Seyyum, all of which proved to be box office hits. Cho played the role of a bike mechanic in the play
Petralthan Pillaiya, written by Pattu of the United Amateur Artistes (UAA), which became a huge success. When the play was later adapted into a film by director
A. Bhimsingh,
Sivaji Ganesan persuaded Cho to play the same role in the film too, leading to Cho's entry into the film world. Cho and Jayalalithaa have worked together in 19 films and also had been part of the same drama troupe.
