Vivek's wife Priyanka Alva Oberoi, who hails from Karnataka, has been helping him get the nuances and intonations of Kannada right. "Since Vivek plays a gangster-turned-businessman based in Bangalore, there are several scenes that require him to speak in that language fluently. He will also be dubbing for the movie in Kannada," says a source.

Vivek says, "Muthappa Rai is a larger-than-life character who belongs to Bangalore and therefore, it is important to get the minutes of his mother tongue right. Learning Kannada is tough, but I am happy and blessed to have an instructor right here at home."
