Dal y Mellt Season 2

The producer said he hoped the financial impact of global success would help nurture future writers with Welsh stories to tell.

"There are so many voices and so many stories to be told," he said.

The Welsh TV and film industry delivered a turnover of £460m in 2023, according to Welsh government data.

For Siwan Morris, who stars in both series of Dal y Mellt, it was "lovely" for her Welsh-language work to be available to friends and colleagues abroad.

"I had friends in Ireland contacting me to say: ＇Hey, I＇ve just seen you in Dal y Mellt,＇ which was brilliant," she said.

An international television market with a global audience is a golden opportunity for Welsh-language programmes, according to film and television critic Gary Slaymaker.

"To normalize the idea that the Welsh language is part of that is great," he said.

"With the advent of streaming channels, suddenly it＇s become very democratic, there＇s a real opportunity if you have the right story."

"I hope we can build on the success of the first series," added Huw Chiswell, the director of Dal y Mellt.

"You feel that there is something special there - that the Welsh language is getting a lot of attention - it＇s surprising how few people are aware of the language."

The new series will be broadcast in Welsh, with subtitles, on S4C, S4C Clic, and BBC iPlayer on January 4 2026
