Rose Tremain says Extra Geography film brings her teenage friendship story into the present

Rose Tremain has welcomed the new film adaptation of her short story Extra Geography, telling the Guardian in an interview published on 1 October that its account of teenage friendship still feels relevant. The film moves her girls’ boarding-school story from the 1950s to the early 2000s, ahead of a cinema opening listed for 2 October by the Irish Times.

The film follows Year 10 friends Minna and Flic, played by Galaxie Clear and Marni Duggan, at a boarding school in northern England. Their decision to fall in love with the first person they see leads them to their geography teacher, Miss Delavigne, played by Alice Englert. Their plan borrows from A Midsummer Night’s Dream, which also becomes the school play that unsettles their friendship.

How Extra Geography updates Rose Tremain’s story

Tremain’s semi-autobiographical short story was first published in 2007 and set in the 1950s. Playwright and screenwriter Miriam Battye adapted it for the film, which is directed by Molly Manners. The shift in period gives the characters a different school life while retaining the story’s focus on how intensely two friends can depend on each other.

Tremain told the Guardian she was delighted with the adaptation. Battye had suggested at their first meeting that the story could transfer to a more recent setting. Tremain said that made her pleased it was ‘not just a little relic from my past’ and that it had ‘relevance now’. She also praised the material Battye invented to expand a five-page story into a feature film, saying the screenwriter had understood it while making it her own.

Why the film centres on Flic and Minna’s friendship

Battye told the Guardian she connected with Flic and recognised the pressure the girls put on themselves to become something significant. She had attended an ambitious girls’ school in northern England, though not a boarding school. She said she brought more of that impatience and intensity into the film.

Manners described the scale of teenage feelings as central to her approach. Small events can feel enormous at that age, she told the Guardian, and she wanted the film to reflect that. She called early female friendships ‘huge romances’, a description of the emotional weight of Minna and Flic’s bond rather than a claim about every friendship.

Duggan, who plays Flic, offered a similar personal account. She told the Guardian that she had experienced intense friendships at 14 and 15, and that a friendship breakup could feel worse than a romantic one. Her comments explain what she recognised in the character; they do not establish how audiences will respond to the film.

The girls’ closeness is also a source of competition. In its review, the Irish Times describes Flic and Minna as constantly measuring themselves against one another. A joint production of A Midsummer Night’s Dream brings boys from a neighbouring school into their enclosed world, while the casting of the play becomes another point of friction between the friends.

The boarding-school setting and the film’s release

Manners told the Guardian that setting the film before social media helped make the school feel isolated. She recalled limited access to a payphone and said few of the girls would have had mobile phones. The production filmed at a dilapidated country house in North Yorkshire; Manners said the crew called the fictional school the ‘cold cradle’ because its pupils had little useful adult support.

Independent reviews have focused on the friendship as well as the film’s comedy. The Irish Times calls the girls close but fiercely competitive, and describes the adaptation as a story of exaggerated adolescent stakes. In an August review, Cinema Perspective also identified their alliance, the school play and the conflict between them as the film’s central strands. Those are critics’ assessments, not evidence of audience reaction.

The Irish Times lists Extra Geography as a 94-minute film with an Irish 15A classification and says it opens in cinemas on Friday, 2 October. Its review also says the film’s historical period is deliberately indistinct. The Guardian places the story broadly in the early 2000s, without specifying an exact year.
