Rajinikanth watched the Kannada film
Jogi and liked it. He encouraged his then son-in-law
Dhanush to accept
Keyaar to star in its Tamil remake. The film was titled
Parattai Engira Azhagu Sundaram, paying homage to Parattai, a character played by Rajinikanth in
16 Vayathinile (1977). When Rajinikanth initially wanted to portray the lead role, he approached
Prem, the director of the original, to direct the remake, but Prem declined as he did not want to pander to the lead actor's popular image at the cost of
realism. Dance choreographer
Raju Sundaram was selected to direct the film but later he was replaced by
Suresh Krissna. Sundaram opted out of the film due to his assignments as choreographer. The film was launched on 31 August 2006 with a
puja. Archana, who was part of the films directed by
Balu Mahendra agreed to play the mother of Dhanush. To portray his role in the film, Dhanush grew his hair out. One of the songs was shot at
Senji fort. == Soundtrack ==
