Bobby Simha is an Indian film actor who has appeared in Tamil, Telugu and Malayalam language films. He was born on 6 November 1983 in Kodaikanal, Dindigul district, Tamil Nadu, India. Since school days, he wanted to become an actor like Rajinikanth. He pursued a bachelor's degree in computer science to satisfy his parents. He was a college dropout, who decided to build a career in business or earn money through BPO. But he landed in movies instead. He got acquainted with short filmmaker Manikandan, who recommended his name to Karthik Subbaraj, who was to make his maiden directorial venture, Pizza. Though his role as house owner ghost was brief, it was one of the pivot roles of the movie indeed. The movie had only less number of artists and made on a moderate budget too. After scaring the audience in Pizza, he made brilliant performances in Soodhu Kavvum and Neram.

He owns a distinct style in delivering comedy scenes on screen. His antagonist role in bi-lingual 'Neram' is one of such instances. He played the role of a 'ghost' in 2012 thriller-Pizza. He played the pivot role of Pagalavan in 2013 highly acclaimed black comedy movie, Soodhu Kavvum. Naan Rajavaga Pogiren and Kadhalil Sodhappuvadhu Yeppadi are his other noted appearances. He has signed 5 movies and is now a busy actor in Collywood. Simha's subsequent performance as the Madurai gangster Sethu in Karthik Subbaraj's Jigarthanda (2014) won him positive reviews from critics and the National Film Award for Best Supporting Actor. After Jigarthanda he played a lead role in the Malayalam film Beware of Dogs, while in Aadama Jaichomada he played Bhoominathan, a "serious, intelligent cop but with a comic touch". The success of Jigarthanda had created opportunities for Bobby Simha to become a lead actor, though several of his subsequent films did not perform well commercially. In 2016, he appeared in the coming-of-age drama, Bangalore Naatkal, where he portrayed a softer role in comparison to his earlier action films. Simha had offered his own dates to the producers to portray a character in the film, with his performance receiving mixed reviews.
