Lily Allen's half-sister Teddie-Rose Malleson-Allen is set to follow in the footsteps of her famous family by making her acting debut. The nine-year-old will play Tatty Walker in the BBC Films remake of Swallows and Amazons, based on Arthur Ransome's classic novel.
Teddie-Rose takes one of the lead roles in the film, and looked to be having fun as she filmed scenes in Calderdale, Yorkshire on Monday. The newcomer was seen getting a piggy back from her co-star Orla Hill as they filmed a carnival scene for the 1930s-set feature-length drama.

The youngster will have plenty of acting advice on hand from her family; her father Keith Allen has starred in a number of films and TV shows including Trainspotting, while her mother Tamzin Malleson is known for her roles in Teachers and Midsomer Murders.
Half-brother Alfie Allen has also established himself as a successful actor with a leading role in Game of Thrones since 2011.

Filming of the remake began in July, with Call the Midwife director Philippa Lowthorpe directing the cast which includes Rafe Spall as Captain Flint, the uncle of the "Amazons" Nancy and Peggy Blackett.
Also set to appear in the drama are Sherlock actor Andrew Scott, Game of Thrones star Gwendoline Christie and Harry Enfield. The comedian has links to Teddie-Rose's family as he was in a relationship with Keith's ex-wife – and Lily's mother – Alison Owen for several years until 1995.

Although producers have changed the name of Teddie-Rose's character, they have promised to stay true to the premise of the original books in which children were allowed to explore and go on adventures without parental supervision.
Christine Langan, head of BBC films, said: "There's nothing like being left adrift, far away from mum and dad. I think a modern audience will be inspired by the amount of independence these children have."
