Martin Parr shows his sweet tooth in this new film

I’m so happy the Teddy Grays family let Magnum photographer Martin Parr loose with a camera in their 194 year-old sweet factory, otherwise this documentary might never have existed. A beautifully intimate portrait of a family business frozen in time, with characters almost as old as the copper pots, who painstakingly churn out endless pear drops, pineapple chunks, cola pips and minty humbugs in the same way as generations before them. It’s working-class Wonka, and like watching the industrial revolution take place before your very eyes.
