Upon arriving at Brandham Hall at the start of Joseph Losey’s 1971 film The Go-Between, Leo Colston (Dominic Guard as a child, Michael Redgrave as an adult) finds much to impress and even overwhelm him: the size and grandeur of the house itself, the paintings covering its walls, the shining silver arrayed in perfect neatness on its tables. He’s particularly struck, however, by two living things. The first is Marian Maudsley (Julie Christie), clad in white and half-hidden by a white parasol as she lounges in a hammock; the second is a deadly nightshade growing on the property. “Atropa belladonna,” Leo explains to his friend Marcus (Richard Gibson), Marian’s younger brother. “It’s poisonous. Every part of it is poisonous.” Beauty masking poison — a symbol, it will turn out, not simply of Marian herself, but of Brandham and upper-class English society as a whole.
