Oscar-nominated actor Pete Postlethwaite has died, a spokesman announced today. He was 64.

Mr Postlethwaite received his Oscar nomination for his performance as Guiseppe Conlon in the 1993 film In The Name Of The Father, about the wrongful convictions of the so-called Guildford Four for an IRA bomb attack.

In it he starred alongside his friend and fellow actor Daniel Day-Lewis and Emma Thompson.

Mr Postlethwaite and Mr Day-Lewis had previously worked together in repertory theatre in Bristol during the 1970s.

Pete Postlethwaite’s other films included Brassed Off, The Usual Suspects, The Shipping News, Inception, Romeo & Juliet and The Town.

Born in Warrington, he had originally planned to be a priest. He later became a teacher but eventually followed his passion for the stage, beginning his career at the Everyman Theatre in Liverpool where he rubbed shoulders with such future stars as Bill Nighy, Julie Walters, Alan Bleasdale, Jonathan Pryce, Matthew Kelly and Anthony Sher.

In 2008 he returned to the Everyman to play the lead in King Lear, a role that he had always wanted to play.

The performance was one of the highlights of Liverpool’s year as the European Capital of Culture.

Mr Postlethwaite was also a political activist who marched against the war in Iraq, supported the Make Poverty History campaign and starred in the 2009 film about global warming, The Age of Stupid.

He also adapted his home to become environmentally-responsible, installing a wind turbine and other features.

He is survived by his wife, Jacqui, his son Will and daughter, Lily.

Mr Postlethwaite, who lived in rural Shropshire near the Welsh border, was treated at the Royal Shrewsbury Hospital.

He recently paid tribute to the staff there, telling the Shropshire Star: "They have been wonderful and I am grateful to them.

"I cannot thank them enough for everything that they have done for me."
