Both Arya and Sathya went through many scripts before selecting the script of
Kadhal 2 Kalyanam, in which Sathya would be essaying the role of a radio jockey.
Sathya, after being assigned for the role, had visited Bollywood actor Anupam
Kher's acting school in Mumbai to "hone his acting skills", before starting to
shoot. Divya Spandana signed the film in October 2008, shortly after completing
her third Tamil film Vaaranam Aayiram, describing her character as a
"career-oriented, independent woman in the corporate world.
The film's shooting, however, got stalled midway in 2009 due to unknown reasons
and was resumed in 2010 only. In July 2010, two songs were canned; the final
song, the "bachelor song" ("Naa Vetta Pora Aadu") was filmed in Chennai, in
which Sathya and Divya, along with junior artists, took part. Art director
Rajeevan had erected a special "jungle set" at AVM Studios for the song, which
was choreographed under the direction of Dinesh. With the completion of the
song, the shooting was eventually finished after one-and-a-half years.
