As of now, I haven't come across any movies or books centered around a Siddharth Roy with a true - story basis. However, it's possible that in certain niche markets or local communities, there could be something in the works or already existing that we just don't know about. There are so many stories out there that it's hard to keep track of all of them.
I'm not aware of any movies or books specifically about a Siddharth Roy based on a true story at the moment. It could be that it's a relatively unknown or new story that hasn't gained widespread attention yet.
There might be some independent or regional works that are based on Siddharth Roy's true story, but without more information, it's difficult to determine. It could be that his story is being told in a documentary - style film in his hometown or in a self - published memoir. But in the mainstream media, there doesn't seem to be any prominent movies or books about him as far as I know.
