Featuring an ensemble cast of Suhasini Maniratnam, Bhama, Kevin McGowan, Abbas Mirza, Nizhalgal Ravi, Michael Lieber, amongst others in supporting roles, the film was set in the early 1900s, tracing the life of Ramanujan, and shot across five different locations, across India and England, which includes Kumbakonam, Namakkal, Chennai, London and Cambridge.

The film features, music and background score composed by Ramesh Vinayagam, cinematography handled by Sunny Joseph and editing done by B. Lenin.

Set in the early 1900s, the film traces the life of the prodigious math genius Srinivasa Ramanujan from the time he was a young Tamil Brahmin to his years in England, where he attended Cambridge University during World War I.

[14] The soundtrack album of Ramanujan, which features eight tracks, including four songs and four instrumentals, was released at the Suryan FM radio station in Chennai on 13 June 2014 to positive reviews from critics.

[17] On 9 July 2014, the producers of Ramanujan arranged a special screening at the Rashtrapati Bhavan, receiving an invitation from the president Pranab Mukherjee.

The Deccan Chronicle called Ramanujan "a brilliant piece on canvas with edifying moments and relevance to modern age" and went on to add that it was "not to be missed", giving it 3.5/5 stars.

[20] Gautaman Bhaskaran of The Hindustan Times gave the film 3/5 stars and wrote, "The movie is a poignant look at the way a prodigy struggled and suffered in a penurious family, a mastermind whose mathematical wizardry invited ridicule and revulsion in far lesser mortals.

Rajasekaran, who also scripted the film, takes us through a linear narrative to tell us about the intelligence of boy Ramanujan as he completely foxes his school-master with a little insight into the importance of zero, and later about his frustration when he hits a wall in his quest to sink into, and shine, with numbers".

[22] IANS gave it 3/5 and wrote, "Gnana Rajasekaran certainly knows the art and succeeds narrating an inspiring tale, but his work doesn’t resonate deep within.

This is so because the director merely recreates several important episodes from Ramanujan’s life on the screen while ignoring the need to build a screenplay to keep the viewers hooked".

The staging is somewhat old-fashioned (read dated), the pacing staid and the film often slips into the kind of melodrama that you nowadays find in TV serials.".

Abhinay Vaddi, the grandson of veteran Tamil film actor Gemini Ganesan done a good job and made justice to their roles.".
