 In 2018, he acted in four Telugu action films with others lead actors, namely "Naa Peru Surya, Naa Illu India", "Bharat Ane Nenu", "Saakshyam" and "Devadas".In his early days as an actor, R. Sarathkumar was considered to be close to All India Anna Dravida Munnetra Kazhagam (AIADMK) supremo Jayalalithaa.However, Sarath's proximity to Jayalalithaa landed him in deep trouble when the film "Nattamai" (1994), which was still running in Tamil Nadu theatres, was aired by Jayalalithaa's television channel JJ TV, using a videotape, which Sarathkumar gave her for personal viewing at her residence.
