In Robin Robin, when an egg falls from the nest, a hatchling is
adopted by a family of mice and raised as one of their own. Not
quite a bird and not quite a mouse, but full of determination.
Robin sets out on an adventure to prove herself and just maybe,
get a sandwich.

The stop-motion special will feature the voices of: Gillian
Anderson (The Crown) as Cat, the villain of our story who just so
happens to know a place where everything is welcome, her tummy;
Richart E. Grant (Can You Ever Forgive Me?) as Magpie, an
obsessive collector of shiney 'stuff; Adeel Aktar (The Big Sick)
as Dad Mouse, a caring but cautious soul who is single-handedly
raising a family of five children; and Bronte Carmichael
(Christopher Robin) as Robin.

Robin Robin is directed by Dan Ojari and Mike Please. The short
film hails from Aardman Animation, an acclaimed British animation
studio who are best known for their works on Flushed Away, Chicken
Run, and A Shaun the Sheep Movie: Farmageddon.
