Judi Dench and Dustin Hoffman are set to star in Roald Dahl’s Esio Trot for BBC One.
The 90-minute film has been adapted by Richard Curtis and will be directed by Irish woman Dearbhla Walsh who won an Emmy for Little Dorrit in 2009.
The film is due to start filming next spring in London.
BBC One Controller Charlotte Moore said of the commission "It's an honour to have Dame Judi Dench and Dustin Hoffman starring in this wonderful new adaptation. It's absolutely stellar casting for one of the nation's favourite children's classics."
In the classic children’s tale Mr Hoppy (Dustin Hoffman) is a retired bachelor, who harbours a secret passion for his neighbour, the lovely Mrs Silver, (Judi Dench). Unfortunately she lavishes all her affection on another... Alfie, her pet tortoise.
