Veteran cinematographer Ravi K Chandran spoke about working with Pawan Kalyan in his latest commercial pot boiler They Call Him OG in an interview with us. They Call Him OG cinematographer Ravi K Chandran on Pawan Kalyan, “He went to Japan to learn martial arts”What was it like working with Pawan Kalyan in OG? I'm thrilled to be working with Pawan Kalyan sir for the second time, after our successful collaboration on Bheemla Nayak. As a former director himself, Pawan Kalyan sir brings a unique understanding of filmmaking techniques to the set. What strikes me most about Pawan Kalyan sir is his well-read, classy, and compassionate personality.
