But perhaps Aardman and Ms Kelly are missing a trick. Ms Kelly is a former pupil at Westminster school, where one of her contemporaries was Helena Bonham Carter, the voice of "Lady Campanula Tottington" in Curse of the Were-Rabbit.
Should Aardman's technical wizards dub the voice of Bonham Carter, great grand-daughter of Herbert Asquith, over Kelly's voice - which some find rather flat and inspid - too? It could make all the difference to her political career.
