Jenny Agutter was embarrassed when doing the scene of her swimming naked in the lake, so as many as possible of the crew were sent away.
Beauty and eroticism are in the eye of the beholder.
She gained mainstream exposure for her starring roles in The Snow Goose, Equus, An American Werewolf in London, The Survivor, Call the Midwife, etc.
There was no one around, apart from Nic in the distance with his camera.
An American Werewolf in London 1981.
