It is known news that the award winning director Pandiraj is currently busy with the shooting of his new movie Kedi Billa Killadi Ranga. This has Vimal and Sivakarthikeyan as the main heroes.
 
Recently he was sharing his thoughts when he reportedly mentioned that the film is about two heroes, two heroines and two villains so a title which had duality was his intention.
 
Not only that, superstar Rajinikanth had done films like Billa and Ranga way back in the 80s which became major hits. That is also one reason which is said to shape up the title like this.
