As Bristol claymation legends Aardman's new film hits screens, Ellen E Jones and Mark Kermode look at the enduring appeal of the most painstaking and time-consuming art form conceivable - stop motion animation.

Ellen talks to director Guillermo del Toro about his 2022 Oscar winner Pinocchio, as well as some of his favourite stop motion films, from Jason And The Argonauts to The Nightmare Before Christmas.

And Mark speaks to animation professor Maureen Furniss and up-and-coming animator Joseph Wallace about why stop motion is so subversive - and so cool.
