O'Neal calls the film his "love letter'' and knew that if he sold it to Hollywood that the film never would have been shot in Kansas.
O'Neal received a medical degree from the University of Kansas and practiced medicine for 20 years, most of it while in the Air Force.
After deciding to become a screenwriter, O'Neal enrolled in a graduate program at UCLA, where he received a master's of fine arts degree in screenwriting.
