RGV's obsession for directing films based on underworld is well-known. He is one of the best directors at filming real-life drama and now the maverick director is all set to make a film based on the life of former underworld don Muthappa Rai.

He said that he is fascinated with the Bangalore underworld after meeting Rai and decided to make a film based on his life. RGV described Muthappa Rai as the 'Baahubali' of underworld. He titled the film as 'Appa' with the tagline "The father of all Godfathers".

In a series of tweets, RGV wrote :

"Had a most amazing meeting and a most fascinating understanding of the Banglore underworld. Banglore underworld has a far more viscous quality which explains its pan india effect nd it's links to Mumbai and Dubai based Underworld. After all my understanding what I had of the underworld I realised today that the D Company is much less in comparison to B Company.To just call it Banglore Underworld is not justified because today I realised that Banglore underworld is actually the Indan underworld.The name of my film on the Banglore Underworld is going to be "Appa" and the tagline of "Appa" is going to be -The Father of all Godfathers.I always thought Godfather was a fictional character but after Meeting Mutthappa Rai realised he is real and he is father of all Godfathers. Mutthappa Rai I think is the Bahubali of the Underworld" (sic)
