It is learnt that the story begins with an episode set in the 12th century, and
then looks at coincidences. In this, Kamal plays Nambi, a staunch V aishnavite
priest. Lyricist Vaali’s lines - ‘Kallai mattum paarthal kadavul theriyadu,
kadavul mattum paarthal kalladi theriyadu…” powerfully describe the character’s
devotion in playback singer Hariharan’s voice.
The other characters are an American, a Chinese man, a CBI officer from Andhra
Pradesh, an old lady, a leader from Afghanistan, a Scheduled Tribes’ leader,
George Bush, a Punjabi and one character, who looks like Kamal normally does.
The film apparently has a very simple screenplay sans usual elements of
commercial films such as duets and unwarranted action. The actor has dubbed for
all the characters, modulating his voice appropriately. Besides watching a lot
of video recordings of George Bush, the actor also put in extra efforts to get
his tone and accent right. He also took the help of daughter Shruti while
attempting to perfect the accent.
