Adventurous Harold (Zachary Levi) is a character in a book who can make anything come to life simply by drawing it. After he grows up, he draws himself and the other characters off the book's pages and into the real world.

Harold finds he has a lot to learn about real life — and that his trusty purple crayon may set off more hilarious hijinks than he thought possible. When the power of unlimited imagination falls into the wrong hands, it will take all of Harold and his friends' creativity to save both the real world and his own.

Harold and the Purple Crayon is the first film adaptation of the beloved children’s classic that has captivated young readers for decades.
