Banerjee also said both neighbours will end up paying a "heavy price" if these incidents continue.
"I can't comment on the film. I haven't seen it. I can't comment if the ban is justified or not. All I can say is it's sad.
"Whatever is happening in India and Pakistan is not only sad, but also foolish," Banerjee told IANS here Friday on the sidelines of the Tata Steel Kolkata Literary Meet.
Directed by Neeraj Pandey, the movie revolves around an undercover unit, formed to keep an eye on the movements of terrorist groups and to nix their plans to disrupt peace and harmony.
The film also stars Rana Daggubati, Danny Denzongpa and Taapsee Pannu and has been released in India Friday. The film also features Pakistani actor Mikaal Zulfiqar and Rasheed Naz.
Banerjee said: "Both India and Pakistan are going to pay a very heavy price, very soon, if they do not stop behaving."
