Cast

Production

In January 2026, a Welsh-language Welsh drama film by filmmaker Marc Evans was selected to screen at the Glasgow Film Festival, adapted by Branwen Cennard from the monodrama play Iphigenia in Splott by Gary Owen. Leisa Gwenllian, Tom Rhys Harries, Nel Rhys Lewis, Owen Alun, Carys Gwilym, and Gavin Lee Lewis rounded out the cast.[1] The 2026 edition of the festival highlighted Gaelic and Welsh-language films, which included Effi o Blaenau.[2]

The film had had a production budget of £2.2 million, partly funded by Creative Wales and S4C.[3]

Release

Effi o Blaenau premiered at the Glasgow Film Festival on 3 March 2026,[4] and was released with subtitles in the United Kingdom on 19 June 2026 to cinemas in England, Wales and Scotland.[5] It received several very positive reviews.[6]

Despite a limited opening on 30 screens, the film had the biggest opening weekend of any Welsh-language film[7]; beating the previous record holder Gwledd. It took £30,000 at the UK box office on its opening weekend, compared to Gwledd's £28,000, despite initially appearing on 47 fewer screens[8]. By 3 August 2026 it had taken £215,000 across 125 venues in the UK and Ireland, a record for a Welsh-language film to that date.[3]
