Astronaut's Farmer movie is a VIOLATION OF COPYRIGHT?

The Astronauts Farmer movie is in violation to my book!!!

My book is the national rocket base.

My book is a one manned rocket launch. A guy that has a dream to go into space on a rocket. He builds it in a remote place. The government gets involved.

It's just like this movie. Do you guys think I have a violation copyright case here? I emailed warner bros when my book came out. They said it was a good idea for a movie, but never got back to me. I'm thinking of finding a way to get in touch. They took my book, and modified it. I do have a copyright on it. What do you guys think??
