Gentlemen Broncos
No, it's not a Cowboy movie.
It's Jared Hess next film. The plot is pretty simple:
A teenager attends a fantasy writers' convention where he discovers his idea has been stolen by an established novelist.
Not ground breaking stuff...but it appeals to me very much. I've a had a similar experience when I first attended a comic book convention years ago. A film about plagiarism...should make a good geeky comedy.
