However, it's important to note that:
* Film rights can be acquired. It's possible that a production company could purchase the rights to adapt the novel in the future.
* Popular novels are often adapted. "Ingo" is a well-regarded book with a strong following, which could make it attractive to film producers.
So, while there's no confirmed project at the moment, there's always the possibility that a film adaptation of "Ingo" could happen in the future.
