The Brontë sisters famously grew up in the Yorkshire town of Haworth, and "Emily" is shown to be predominantly set there. As well as it being the setting, Yorkshire also provides the primary shooting location for the film, with scenes being filmed across Haworth and also the village of Dent.
The house that features in the film was the genuine inspiration for "Wuthering Heights." So whilst the film's narrative may be imagined, its setting is very much genuine and accurate to the life of Emily Brontë and her sisters.
