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.
The film Joe was about a man that hired a boy that was 16.
The boy in the film was 15 years old. I think that the ages and numbers were close and the system couldn't distinguish between the two numbers.
