Vidharth is an Indian actor, appearing in Tamil films. He started his career in 2001 doing uncredited roles. His first major role was in Thiruvannamalai, where he played villain, but his next release Mynaa became a huge success. He has also done a film for AVM Productions titled Mudhal Idam.
Vidharth's father was a cook in Singapore and sent money home for Vidharth to be educated, although he described himself as a "very weak student". Vidharth then hoped to become a bus driver, much to the displeasure of his father, and worked in Devakottai, Madurai and Coimbatore. However he became depressed with his occupation and soon left for Chennai, without telling his family, to try to make a career in the Tamil film industry.
He soon joined the drama troupe, Koothu-P-Pattarai through some of his friends and began learning the nuances of acting step by step and made his on screen debut with a small role in Gautham Menon's Minnale (2001). Despite believing that the small role would bring him more offers, it did not, and Vidharth continued small-time work with his drama troupe. After ten years, Prabhu solomon casted him in small role in his films, Kokki, Lee and Laadam, after seeing him in action in Koothupattarai.
His first major role was in Thiruvannamalai, where he played villain. He then collaborated with Prabhu Solomon again, who gave him the lead role in his romantic drama Mynaa. The film became the biggest success of Vidharth's career. He starred in AVM Productions' 175th production Mudhal Idam. In Kollaikaran, he played the role of a criminal. In 2014, he had five releases, the most in a year in his career.
He first acted alongside Ajith Kumar in the masala film Veeram. Venmegam was his next release, which was said to be about the bond between an artist, played by Vidharth, and a school girl (played by Jayashree Sivadas). He then played a mini bus driver named Velpandiyan in S. P. Rajkumar's romantic comedy Pattaya Kelappanum Pandiya.
His other releases that year were Aal, a remake of the Hindi film Aamir and reportedly the first Tamil film to be shot in Sikkim at the India-China border, and Kaadu, a film based on the subject of deforestation. With regard to Kaadu, The New Indian Express wrote that it had Vidharth's "most inspired performance post Myna".
He married Gayathri Devi in 2015 and they have a daughter.
