Sunil's career began on a slow note with movies like Second Hand (which was stopped from production), and Peruleni Cinema. Prema kadha and Swayamvaram were his first real opportunities in the industry. Chiru Navvuto and Nuvve Kavali were the first films that he acted in. Nuvve Kavali was the first one to release.
Sunil was cast in the lead role in Poola Rangadu, which was released across 450 theatres worldwide. The film received positive reviews.
