Effi o Blaenau (Effi from Blaenau) is an adaptation of Gary Owen’s play, Iphigenia in Splott, but relocated from Cardiff to Gwynedd.
Directed by Marc Evans, whose previous work includes Mr Burton, the film follows Effi as she navigates being out of work, clubbing and hangovers.
A chance encounter at a nightclub with injured soldier Lee, played by actor Tom Rhys Harries, gives Effi a brief glimpse at a different life – until a difficult reality follows.
Evans said the distribution of the film, at major cinemas across the UK from Friday 18 June, was “amazing”.
“One of the ambitions of making a film in Welsh is that it’s not just shown to Welsh people… it travels,” he said.
“One of the joys of cinema is being transported to a place that you didn’t know of before or another culture, another language.”
