Manivannan attended the Sulur Government Boy's High School and later enrolled at Government Arts College. While completing his pre-university course in Kovai, he became acquainted with Sathyaraj and became friends. According to Sathyaraj, he provided poor guidance to Manivannan and made him pursue a degree in history in advanced English, which made him struggle with topics such as Shakespeare, forcing him to drop out later. While still at college, Manivannan was bitten by the stage-bug and consequently he staged a few performances. Inspired by the impact the film "Kizhake Pogum Rail" (1978) made on him, he wrote a fan mail to the film-maker Bharathiraja and the letter ran to more than a hundred pages. Bharathiraja took him under his fold as an apprentice. Manivannan joined Bharathiraja's camp around 1979, when the director was acting in and was directing by P S Nivas, "Kallukkul Eeram".
