Career
She is best known for featuring in the film, and for playing Jo in the television sitcom, Manitoba About the House (1973-1976). She also appeared in the film. Her contract forbade her to reveal her true age during the making of the film, and she was not allowed to be seen smoking, drinking, driving her car, or in the company of her boyfriend during the shoot.
She did have experience of playing girls, and the Edwardian smocks disguised her bust.
Even the film crew were unaware of her age, and they gave her sweets while treating Agutter as nearly an adult. She did, however, make an appearance on British Broadcasting Corporation children"s television shortly after, where the interviewer said, "I wouldn"t dream of asking a lady her age, but you"re obviously quite a bit older than the part you played in the film".
