LONDON — Albert Finney, the British stage and film actor who defined an era’s rage and frustration in dramas of blue-collar realism and social revolt and went on to find stardom in Hollywood, died on Thursday in London. He was 82.

His death, at the Royal Marsden Hospital, was confirmed by Jon Oakley, a partner at Simkins, a law firm that represents the Finney family. The cause was a chest infection, he said.

Mr. Finney became one of his generation’s finest and most honored actors over six decades. A frequent nominee for an Oscar and Britain’s equivalent of one, the Bafta, he was a star as comfortable in movies like “Tom Jones,” “Murder on the Orient Express,” “Under the Volcano” and “Erin Brockovich” as he was on the classical British stage.

He first came to wide attention alongside contemporaries like Alan Bates and Tom Courtenay, actors collectively known as “angry young men” — counterparts to the playwrights and novelists who shared that sobriquet. Together they helped turn Britain’s gaze inward, toward gritty industrial landscapes, where a generation of disaffected youth railed against the class system and the claustrophobic trap it laid for workers locked in dead-end jobs.
