Mark Cousins follows his 15-hour opus The Story Of Film with a comparatively bite-sized discourse on how world cinema has depicted childhood.
The result is a dizzying compilation of clips connected, rather preciously, by footage of his niece and nephew playing with marbles.
Cousins introduces excerpts from some 53 titles that range from the reassuringly familiar ( E.T. , Meet Me In St Louis ) to the bafflingly obscure.
Our host’s lilting voiceover remains an acquired taste, but his boundless passion is never in question.
