Enda Walsh will be adapting the screenplay, which follows three aunts who go around the world collecting unhappy children. They bring them back to the Island of the Aunts, where they will be loved forever.
Eva Ibbotson's literature has been compared to Roald Dahl's, and it is suspected that Island of the Aunts will be a mix of live action and animation, similar in style to both The Mighty Boosh and Bunny and the Bull.
The film is being produced by BBC Films, and will be released Overseas sometime in 2012. There are no plans to release Island of the Aunts in the states at this time.
