Harold and the Purple Crayon sees the iconic storybook character come to the real world to find his “Old Man” and discover why he was ever created. The 2024 movie puts a fresh twist on the 1955 picture book of the same name by Crockett Johnson, first detailing how the familiar little boy in a onesie grew up in his world of imagination. However, when the narrator of Harold’s world, whom he had dubbed his Old Man, seemed to have vanished, Harold (Zachary Levi) went on an adventure with his friends Moose (Lil Rel Howery) and Porcupine (Tanya Reynolds) to the real world to discover what had become of him.
