premise: Joe is a 2013 independent drama film directed and co-produced by David Gordon Green, co-produced by Lisa Muskat, Derrick Tseng and Christopher Woodrow and written by Gary Hawkins, adaptation from Larry Brown's 1991 novel of the same name. It stars Nicolas Cage and Tye Sheridan, revolving around a tormented man who hires a 15-year-old boy and protects him from his abusive father.
hypothesis: Joe was a book before it was a film
reason: Both the years listed and the word "adaption" indicates that the book came first and the film was based upon the book.  I think it was difficult for the system because it had to understand what a "adaptation from Larry Brown's 1991 novel of the same name" means
