Wait, maybe it's a recent or less-known film. Let me think. There's a 2017 Bengali film called "Paper" where Mithun Chakraborty plays a role. Directed by Sudeshna Roy and written by Soumitra Basu. The story revolves around a man who discovers unsent letters from his past love. The film explores themes of nostalgia and memory. Mithun's character is named Abhirup Roy. The cast includes Debjit Datta and Priya Chatterjee. It's a drama with artistic elements. The movie was well-received for its storytelling and Mithun's performance. The user might be looking for the plot summary, cast details, or where to watch it. I should mention the director, writer, main characters, and highlight the themes. Also, note that it's a 2017 release. Maybe include some reception info, like awards or critical reviews if available. Need to confirm the details to avoid inaccuracies. Also, check if there's another movie with a similar name or if it's known by another title. Ensure the information is accurate and presented clearly.
