Screenwriting is the art and craft of writing for film, television or video games.
- [Screenwriting] is no more complicated than old French torture chambers, I think. It's about as simple as that.
- It seems to me it's the hardest thing 'cause you're starting from nothing and creating something. Everybody else is interpreting what you've written. Everybody else is an interpretive artist. Even the best of them. Stanley Kubrick was an interpretive artist. The best actors in the world are interpreting what's on the page, and they use it as a springboard to something else, but if it's not there, there's nothing to spring from. So the writer is the only person who's taking absolutely nothing, and 120 pages of it, and dirtying it up in such a way that it's gonna gross hundreds of millions of dollars and make a lot of people happy.

- I'm a first-generation TV brat. My brain was welded to the solid-state circuitry of our RCA Viewmaster black-and-white television set. Every day and night I saw all the past, present, and future pulp the tube had to offer. Plus there were comic strips, my family, and other illustrators.
- George Shrinks is King Kong in reverse. Nicholas Cricket is Casablanca with bugs. In The Leaf Men and Bently & egg the characters are as dashing and heroic as Robin Hood. In Santa Calls there are elements of The Wizard of Oz, Davy Crockett, The Lone Ranger, Rin-Tin-Tin, Little Orphan Annie, Jules Verne, and the Warner Brothers cartoons. For Dinosaur Bob I thought about Paul Bunyan and Casey at the Bat. Not only does a dinosaur become the family pet, but he also plays baseball and the trumpet, and dances the hokey-pokey. A Day With Wilbur Robinson is a combination of Dr. Doolittle, The Absent-Minded Professor, Invaders from Mars, and an exaggerated version of my own childhood.

- A rule says "You must do it this way". A principle says, "This works... and has through all remembered time." The difference is crucial. Your work needn't be modeled after the well-made play; rather it must be well made within the principles that shape our art. Anxious, inexperienced writers obey rules. Rebellious, unschooled writers break rules. Artists master the form.

- Well, Jack Warner may have been celebrated for calling writers "Schmucks with Underwoods," but 20 years earlier Irving Thalberg … said, "The most important person in the motion picture process is the writer, and we must do everything in our power to prevent them from ever realizing it."
- This...is why screenwriting pays so well. They don't pay me to write. I'd write for free. They pay me NOT to punch people in the neck.

- Every writer is a frustrated actor who recites his lines in the hidden auditorium of his skull.
