The first image and audio of Michael Sheen as Owain Glyndŵr have been premiered today to mark the annual day which commemorates the iconic Welsh prince. 

On 16 September 1400, Glyndŵr was proclaimed Prince of Wales by his followers, kickstarting a 15-year rebellion against Henry IV’s English rule. This vital part of Welsh history will be brought to life in Gary Owen's epic new play Owain & Henry in November 2026.

In the photograph shared today, Sheen is seen as Owain through the lens of photographer Kirsten McTernan. In an audio release on social media, we hear the actor and Welsh National Theatre artistic director as Owain for the first time, speaking these words:

This island has been home to many kingdoms. 
First my people, the Cymry.
Then came the Romans, the Vikings. The Angles and Saxons. The Flemish. The Normans.

We spoke a dozen languages from a dozen nations.
And then this hotch-potch of peoples became simply England.
Now only Sacson may be spoken at England's court,
And the oldest tongue of this island is called foreign.

Today, we teach the Sacson that this island
Was only ever theirs to share.
