I want to know the answer to the following question:
Who are the only screenwriters Spielberg has worked with on more than one film?
All the background I'm provided with is that "A famous example of Spielberg working with the same professionals is his long-time collaboration with John Williams and the use of his musical scores in all of his films since The Sugarland Express (except Bridge of Spies, The Color Purple and Twilight Zone: The Movie).". Is that enough to answer the question?
Answer: no
