The Pumpkin Eater (1964)

Screenwriter Jake Armitage (Peter Finch) and his wife Jo Armitage (Anne Bancroft) live in London with six of Jo's eight children; the two eldest boys are at boarding school The children are spread over Jo's three marriages; only the youngest is Jake's biological child, but he treats them all as his own. Jo left her second husband Giles (Richard Johnson) after meeting Giles' friend Jake; the two were immediately attracted to each other. Their upper-middle-class life is very different from Giles and Jo's; who lived in a barn in the English countryside. But Jo is ruminating about her strained marriage to Jake, with issues on both sides. Jo suspects Jake of chronic infidelity, only confronting him with her suspicions whenever evidence presents itself. And Jo's psychiatrist believes that she uses childbirth as a rationale for sex, which he believes she finds vulgar. These issues in combination have placed Jo in a fragile mental state. They both state that they love each other, but neither seems to like the other much. As they prepare to move back to the English countryside in a new house within sight of Jo's old barn, both Jo and Jake come to their own unspoken individual conclusions of whether their marriage can withstand these strains, and if so what type of marriage it is destined to be.
