Koel Mallick and Parambrata Chatterjee have worked together in many films. But, this is the first time that Koel will be working under Parambrata's direction in Bony. While talking about his experience of directing Koel, he said only good things about the actress. “As a co-actor, when you have worked with someone for a few films you can understand what it would be to direct that same person and Koel is highly focused and co-operative,” he said. Bony is currently being filmed in Milan.
