Speaking about the film, Vincent Selva stated, "The bond between humans and dogs has existed for ages. Renowned directors like Akira Kurosawa and Steven Spielberg have given significant roles to dogs in their films. Similarly, I came across a crime thriller story and decided to develop it into this film."

Richard Rishi plays a police inspector in the movie. A trained Belgian Malinois, a breed widely used in security forces across different countries, plays a crucial role in the film. To establish a close connection with the dog, Richard Rishi trained with it for a month, after which the dog developed a bond with him. The first phase of shooting has been completed, and the next schedule will begin soon," he added.
