Harold and the Purple Crayon is an upcoming American live-action/animated fantasy film directed by Carlos Saldanha from a screenplay by David Guion and Michael Handelman, based on the 1955 children's book of the same name by Crockett Johnson. It will star Zachary Levi in the titular role, with Lil Rel Howery, Benjamin Bottani, Jemaine Clement, Tanya Reynolds, and Zooey Deschanel in supporting roles. The film serves as a sequel to the original book, where, after the adventurous Harold grows up with his magical purple crayon and draws himself off the book's pages and into the physical world, he finds that he has a lot to learn about real life.
