Actor Hannah Waddingham is all set to lend her voice for the upcoming animated film Tiddler from BBC which will release this Christmas.

Waddingham is set to narrate the half-hour special, which will feature Lolly Adefope as Miss Skate, Jayde Adams as Plaice and other characters and Rob Brydon taking on the roles of the Fisherman, Whale, Starfish and Anchovy. Child actors Reuben Kirby and Theo Fraser also star as Tiddler and Johnny Dory, respectively.

Alongside the BBC, the animation is being produced by the Oscar-nominated Magic Light Pictures, based on the popular children’s picture book of the same name by Julia Donaldson and Axel Scheffler.

The film is described as "an underwater adventure about the power of imagination and finding confidence in yourself — and how to be content as a little fish in a big ocean."

According to its official synopsis, Tiddler tells the story of a "small grey fish with a big imagination who gets lost in the deep wide ocean, until he's saved by his storytelling."

"Voicing the narrator for this Christmas special from Magic Light Pictures has been a real joy to record," said Waddingham. "Tiddler is the tale of the storyteller in all of us, and helps children understand what it’s like to be a small fish in a very big pond."

Waddingham, who is best known for playing Rebecca Welton in Apple TV+ smash Ted Lasso, has also starred in prominent roles in films like The Garfield Movie, The Fall Guy, and series like Sex Education and Game of Thrones.
