Michael Sheen says Welsh people should stand up to attacks on culture

On taking on the role of Aneurin – or Nye – Bevan, Sheen said he felt an “emotional and passionate connection” to the Tredegar politician, but said it was also “a lot to live up to”.

The play was written by Welsh playwright Time Price and is a co-production between Wales Millennium Theatre and the National Theatre in London, where it premiered in April – it will play in Cardiff from 18 May to 1 June.

It tells the story of Nye in a series of flashbacks as a morphine-induced Bevan lies in a hospital bed battling terminal stomach cancer in 1960.

Sheen said it is now time for Wales to tell its own stories – despite the squeeze on public funding.

“Walking in here yesterday, walking onto the stage I got a real excitement about the potential for this space, for plays telling Welsh stories, the story of Wales,” he said.

“No one else is doing it. Where is the great play about the Chartists, the Miner’s Strike, our cultural life and history?

“We have to make sure our voices are heard. Even if the opportunities for those voices to be heard are being shut down, then we have to shout louder don’t we.”
