Steven Spielberg is a HUGE animation nerd. He produced Who Framed Roger Rabbit, Tiny Toons Adventures and Animaniacs. It’s his understanding of the discipline for animation that makes his understanding of staging and blocking so great.
The Mr. DNA exposition scene is Spielberg’s first hand-drawn cartoon sequence in a feature film he directed. Kurtz and Friends Animation created the old-school educational style cartoon. Spielberg asked for no changes to the storyboards, pencil tests or the final animation!🦕
