According to the National Institutes of Health, brittle bone disease (Osteogenesis imperfecta) is a genetic or heritable condition that causes bones to fracture and break very easily. Austin LeRette was posed with another challenge growing up when he was diagnosed with autism along with this. The Unbreakable Boy explores the child's story, and also the way his parents tried to adapt to their new lives with a special needs child.

The film explores Austin's story and aims to show the lives of people on the autism spectrum, while also sending out a message of hope and positivity. Scott LeRette, in an interview with People magazine, mentions Zachary Levi's character in the film saying "I wish I could love anything as much Austin loves everything," and says that he thinks about it everyday.

"Because it’s exactly right. Austin would rather gravitate to the worst of human beings to get to know them. Because he thinks everybody’s redeemable," LeRette elaborated.

Today, the actual Austin LeRette is 30 years old and still close to his family. He lives in a semi-independent setup but still requires some assistance in tasks like driving.
