Aparshakti Khurana, who plays a pivotal role in ‘Dhokha - Round D Corner’, was aware that the film would require more intensive prep. The actor was making a departure from his comic roles to essay the part of a Kashmiri terrorist in the R Madhavan, Darshan Kumaar and Khushalii Kumar-starrer. Before director Kookie Gulati took the thriller on floors earlier this year, Khurana trained with a dialect coach for six weeks to perfect his Kashmiri accent.
