 The choice of Siddharth was because of the sheer relevance to the character in real life. However, they finalized the choice of the actor only after the script was ready. The choice of Genelia was based on her natural vivacity in real life. This and her eyes, according to Bhaskar, made her an obvious choice for her character. More so, she liked the one line story that Raju told and also a few scenes that he narrated to her. She immediately liked the character and consented for the role. The fact that her co-actor, Siddharth and she acted earlier together in Boys (2003), made them more comfortable to work with. The camaraderie that the lead actors shared during the filming, added to their good performances. The choice of Prakash Raj was easy as he befitted the character he portrayed while, Jayasudha was persuaded to play the role of the lead actor's mother.
