Several of Morrow's scripts are inspired by real people, especially people with disabilities and/or extraordinary talents. These include the savant played by Dustin Hoffman in the film Rain Man, inspired by the real savant Kim Peek; and mentally disabled Bill Sackter, played by Mickey Rooney in the TV movie Bill. Both of these won writing Oscar, Emmy and other awards for Morrow and for the actors who portrayed them. Morrow gave his Oscar statuette as a gift to Kim Peek. Morrow wrote CBS's Bill: On His Own (1983) and his relationship with Sackter is presented in the feature length 2008 documentary A Friend Indeed – The Bill Sackter Story.
Morrow is a member of the Association of Retarded Citizens, the National Association of Social Workers, and the Autism Society of America.
He is an avid golfer, and is known to play the majority of his golf rounds using an eight club bag of hickory stick (wooden shaft) golf clubs made pre-1940.
