Hi, I think the directing credit belongs to a different James Bruner. Per this short bio text:

James Bruner (Director) - After completing SUMMER CHILDREN, Bruner worked as Production Designer on the dark horror film “Blood Bath” starring William Campbell and genre favorite Sid Haig. He is the father of actress Anne Bruner. B.A. Theatre, Baylor University, M.A. UCLA Film School. Directed Features, Commercials at Film Fair Productions.

If he had also written or co-written 11 feature films my guess is that would have been included. But I did move the two incorrect writing credits. Thanks!
