Harish's first job was as a part of the cabin crew, working with
Paramount Airways for three years and later with
British Airways for three further years. He also briefly worked in a commercials company in Chennai before Suriya Prabhakaran, offered him the lead role in a film. Harish thus made his acting début with the low budget 2010 romantic Tamil film
Tha, which opened to above average reviews. To prepare for his first role he grew his beard for five months, and did work to darken his skin by applying oil and sitting in the sunshine as per the role's demands.
