Zog is a children’s picture book, written by Julia Donaldson and illustrated by Axel Scheffler, about a young dragon eager to earn a golden star at his dragon school. He is helped by Pearl, a princess-in-training who prefers to be a doctor.

Zog was published by Alison Green Books in England in 2010, and in the U.S. in 2012, as A Gold Star for Zog, by Arthur A. Levine Books.

The book was adapted as a film by Magic Light Pictures, directed by Max Lang and Daniel Snaddon, and broadcast on BBC One on Christmas, 2018. In the U.S., Zog began streaming on Amazon Prime on December 16, 2019.

The cast, as listed on Wikipedia:

• Sir Lenny Henry as the Narrator.
• Hugh Skinner as Zog, the orange accident-prone dragon (the main character in the story) who tries his best every day to win a golden star.
• Kit Harington as Sir Gadabout the Great, the knight in the story who, at one point, joins Zog for a fight.
• Patsy Ferran as Princess Pearl, the princess who lives in a castle with her uncle and dreams of being a doctor.
• Tracey Ullman as Madame Dragon, the green-skinned teacher at Dragon School who teaches the dragons throughout the school days.
• Rob Brydon as the Horse, Castle Guards and Additional Voices/Vocals.

French composer Rene Aubry provided the music.
