Development
With A. L. Vijay and Vikram confirming their presence in the project, the producers failed in attempts to persuade Vidya Balan to appear in the film. In October 2010, Anushka Shetty agreed to appear in the lead female role in the film after agreeing terms. Amala Paul, who appeared in the lead role in Mynaa, was signed on to play the daughter of a millionaire in November 2010. She had signed on in place of Meera Jasmine, who opted out of the film before production began. Despite reports that Divya Spandana joined the cast of the film in early 2011, Vijay refuted the claim as a rumour The film saw the collaboration of several technicians who had worked in Vijay's earlier film Madrasapattinam, with G. V. Prakash Kumar as music composer, Nirav Shah as cinematographer and Anthony as editor. Santhanam was appointed as art director, whilst Deepali Noor took charge of costumes.The film proceeded without an official title until April 2011, with several possibilities announced during the production period. The film was tentatively titled Deiva Magan (Son of God), a title from a 1969 film featuring Sivaji Ganesan. However problems arose after Sivaji Productions claimed that they owned the rights of the title and expressed their interest on using the name for a future production featuring Sivaji's grandson, Vikram Prabhu.[9] The title Pitha (Father) also ran into trouble after a debutant team announced that they had registered the title, but subsequently the film was christened as Deiva Thirumagal in March 2011.
Filming
The film was predominantly shot across the hill country settings in Ooty throughout late 2010, with a chocolate factory being constructed as a set by art director Santhanam.[12] Scenes were also shot within Chennai, with the Chennai High Courtroom being reproduced for a scene in the film.[13] The team of the film returned to Ooty in February 2011 to complete the final schedule, after which the film was completed.[14] In order to perfect his portrayal of a mentally challenged adult with the maturity of a five year old boy, Vikram visited Vidya Sagar, a school for children with special needs, to learn and study the behavior of such children.[15]Trailer
