The trailer instantly opens with a racy scene as Colman is flung across her bed in a passionate tryst before flashing back to show how she became the subject of mockery in her village due to her single status. At her behest, Peter then spends a month weaving together a husband for her, who comes to life and ties the knot with her in a chapel. Another racy scene follows as Colman undresses her wicker husband, gasping in awe as she admires his body before being grabbed in a passionate clinch. The villagers, which include Quadrophenia's Phil Daniels, Saltburn's Richard E Grant and The Crown's Elizabeth Debicki, soon grow obsessed with the couple and their relationship – with the men wanting the wicker man ousted, and the women lusting over him.
