Trivia, insights & behind the scenes
Based on Susan Coolidge's 1872 novel 'What Katy Did,' which has been adapted roughly every decade since silent film era — this version notably keeps Katy's disability arc honest rather than magically curing her.
Produced by CBBC as part of a deliberate push for more complex female protagonists in children's television, following the success of 'Hetty Feather' — both series share a production team and that gloriously unhinged energy.
