Before starting Harish Shankar's flick, Varun reportedly trained under the guidance of Olympic gold medalist Tony Jefferies. Now, he is going to get trained by Neeraj Goyat who is the first-ever Indian boxer to enter the world rankings of WBC. He is considered as India's most promising boxer and Varun will be learning the boxing moves and punches from him for the next month.
Apart from that, Hollywood stunt master Larnell Stoval who worked on Salman's 'Sultan' was brought in for this sports drama. Looks like the makers are going all out to bring authenticity for this sports drama produced by Allu Bobby.
