Aidan Turner is set to make his West End debut in a play by Martin McDonagh, The Lieutenant of Inishmore.
The 34-year-old star will take the lead role of Mad Padraic, a member of the Irish National Liberation Army, in the play that has been described as "a brilliant satire on terrorism" and an observation of "violence in contemporary culture."
Turner said he has missed "the buzz" of theatre work and is excited by how different his character will be to that of Poldark's Ross Poldark, for which he is best known.
"It's the furthest I can get from Ross Poldark that I can possibly imagine," Turner told The Daily Mail.
The production will show at London's Noel Coward Theatre and is being produced by the Michael Grandage Company. The Lieutenant Of Inishmore opens for previews on June 23, running until September.
The award-winning play, which is set in Ireland in 1993, was first produced by the Royal Shakespeare Company in 2001.
