David
I'm surprised that no credit is listed for "David" here. He was the little boy with legs in braces who meets Dorrie and kicks the soccer ball.
Unless he's one of the actors listed as "Boy." There's also no listing for Clarence, the older boy who Dr. McDonnell tries to help, but I notice two boys who were about 14 or 15 during filming who could have been him.
