She would go on to have a rambunctious performing career, not only as a stage and screen actress, but as the lead singer of the 1980s new wave band Altered Images, who got signed by CBS Records while the film was in production. Her role in Gregory’s Girl is smaller than the other two leads, but she’s the ace up its sleeve, because of Susan’s wise-beyond-her-years demeanour and her magical chemistry with Sinclair, with whom she has remained close friends over the years.
Her Louise Brooks-esque bob was a convenient way to conceal a recent facial wound, but also – like her beret – sprang fully formed from Grogan’s own precocious aesthetic. Essentially functioning as her own costume designer, she created an iconic look.
“I was really quite fond of silent movie stars,” she tells me. “I mean, I had delusions of grandeur beyond belief, even at that age! So I was quite into the style.
“I didn’t realise what an incredibly privileged position I’d ended up in until afterwards, when the reality of having a career in this business suddenly hits you. When you’re that age, and you think, ‘When I leave school, I’d like to be a film star and a pop star’? That’s what happened. And I will never understand that.”
Despite her self-confident style, Grogan, for many years, was unable to watch herself in the film and, in fact, only watched the full thing in 2015, when the BFI included Gregory’s Girl in a special Love season. She saw it with her then-ten-year-old daughter Ellie, realising that opportunities to catch it on a big screen might not come along too often again, with a child who was “just old enough to get it.”
Idyllic though Cumbernauld looks in Gregory’s Girl, 1980 was actually the worst summer in the area since 1907, and the colour of the football pitch kept changing in the rain. Nevertheless, the cast have fond memories of filming.
