Georgy Girl is a 1966 British romantic comedy film directed by Silvio Narizzano and starring Lynn Redgrave, Alan Bates, Charlotte Rampling, James Mason, and Rachel Kempson (Redgrave's mother).^[3] It was written by Margaret Forster and Peter Nichols based on the 1965 novel of the same name by Forster. The film tells the story of a virginal young woman in 1960s Swinging London, who is faced with a dilemma when she is pursued by her father's older employer and the young lover of her promiscuous, pregnant flatmate. Grossing $16.8 million, Georgy Girl was a box-office success, and it also spawned a hit theme song.

Georgina "Georgy" Parkin is a 22-year-old Londoner who has musical talent, is well-educated, and has an engaging, unpretentious character. She has an inventive imagination and loves children. At the same time, she believes herself to be plain and overweight, dresses haphazardly, and is incredibly naïve on the subjects of love and flirtation, having never had a boyfriend. Her parents are live-in employees of businessman James Leamington, who is in a loveless, childless marriage with the sickly Ellen.

Leamington watched Georgy grow up and treated her as if he were her second father, but as she has become a young woman, his feelings for her have become more than fatherly. On his 49th birthday, Leamington offers her a legal contract, proposing to supply her with the luxuries of life in return for becoming his mistress. Georgy sidesteps his proposal.

Her flatmate is the beautiful Meredith, who is a violinist in an orchestra. While she is out on dates with other men, Georgy entertains her boyfriend Jos Jones, on whom she has developed a crush.

When Meredith discovers that she is pregnant by Jos, they decide to get married, even though she tells him that she has previously aborted two of his children and only wants to marry because she is "bored". After the wedding, Jos moves in with Meredith and Georgy, becomes disillusioned with Meredith, and finds himself attracted to Georgy. Meanwhile, although she uses Leamington's interest in her to convince him to buy several expensive items for the baby, and Ellen dies suddenly, Georgy does not sign Leamington's contract.

In the midst of an argument with Meredith over her cavalier attitude to her pregnancy, Jos kisses Georgy and tells her that he loves her. Georgy flees the apartment, and Jos follows her into the streets of London, shouting his love for her. The two return to the flat, where they have sex, after which Peggy, a neighbor, tells Jos that Meredith has gone into labour, and he and Georgy go to the hospital.

Although Georgy feels guilty, she continues her affair with Jos while Meredith is in the hospital. Meredith has no interest in her daughter, Sara, and has tired of Jos, so she announces that she plans to put the child up for adoption. When Georgy sees Sara, she is smitten.

Georgy and Jos bring Sara back to the flat. It quickly becomes clear that Georgy cares more for the baby than for Jos, and their relationship ends when Jos tires of a father's responsibilities and abandons Georgy and his baby. Now that Georgy is the sole caregiver of a child to whom she has no blood ties, Social Services wishes to remove Sara from her care.

Leamington has been following the developments in Georgy's life. When he mentions modifying his contract to accommodate the recent changes, Georgy, seeing an opportunity to keep Sara, gets him to propose marriage. As the newlyweds are chauffeured away from the church on their wedding day, Georgy ignores Leamington, devoting all of her attention to Sara.

The film was the basis for an unsuccessful^{[citation needed]} 1970 Broadway musical titled Georgy.

In 2013, it was adapted for BBC Radio 4 by Rhiannon Tise.^[20]
