Father Stu is based on Long’s true story, a former boxer whose life spiraled out of control before a fatal blow in a horrific motorcycle accident led him to embrace a life with the cloth.

He entered the seminary in 2003 and was ordained a diocesan priest in 2007, although his life was interrupted by an illness called inclusion body myositis.

Father Stuart Long was just 50 years old when he passed away in 2014.
