A new Welsh horror movie, Gwledd (The Feast), is set for cinematic release this August 19.

The award-winning Welsh language film, said to be "steeped in Welsh folklore", is set in the mountains of Eryri, and explores "the consequences of greed, corruption and man’s exploitation of the earth."

Gwledd - described as a "haunting, slow-burning horror tale" - unfolds over the course of one evening, as a wealthy family gathers for a sumptuous dinner in their ostentatious house, hoping to secure a deal with a local farmer and businessman to mine in the surrounding countryside.

When a mysterious young woman, Cadi, arrives to be their waitress for the evening, the family’s beliefs and values are challenged as her quiet yet disturbing presence begins to unravel their lives - slowly, deliberately and with terrifying consequences.

From Valleys-born director Lee Haven Jones (Doctor Who) and writer and producer Roger Williams (Bang), the film stars Annes Elwy (Little Women, Electric Dreams) as Cadi.

It has so far has won awards from South Korea’s Bucheon International Fantastic Film Festival, Lisbon’s MotelX Festival and Switzerland’s Neuchatel Fantastic Film Festival.

Gwledd, rated 18, is a SGRECH production for S4C, Ffilm Cymru Wales, BFI (awarding funds from the National Lottery) and Melville Media in association with Fields Park.

It is distributed by Picturehouse Entertainment.
