Director Ganana Rajasekaran has proven his mettle and has also shown the amount of hard work he puts into his projects, through his earlier movies. Ramanujan is no less! The amount of effort put into researching the history of the Indian Mathematical genius is evident in every frame. Right from shooting the life of Ramanujan at the very home he was born and brought up in, to the authenticity of the Cambridge campus, the director and the producers have gone the extra mile to get it all right. What better platform could Abhinay, the grandson of veteran actors Gemini Ganesan and Savitri, have gotten to make his Kollywood debut. His performance as Ramanujan is perfect. Bhama, as the cute and bubbly Janaki is good.
