Roy Dotrice, a British stage, film and television actor who began performing as a prisoner of war in Germany and worked in Britain and America for six decades, notably in one-man shows portraying Abe Lincoln, the diarist John Aubrey and other historical figures, died on Monday at his home in London. He was 94.

His family confirmed the death, The Associated Press reported.

Hailed by critics for suffusing his character with fine-tuned blarney, malevolent passions and brooding gloom, Mr. Dotrice won the Tony Award for best featured actor in 2000 for his portrait of the conniving Irish father and pig farmer in an acclaimed Broadway revival of Eugene O’Neill’s “A Moon for the Misbegotten,” with Gabriel Byrne and Cherry Jones.

Reviewing the production in The New York Times, Ben Brantley wrote, “To watch Ms. Jones, Mr. Byrne and Roy Dotrice, who completes the triangle of principal performers, react to one another is to realize the degree to which O’Neill’s last completed play is about how everyone is an actor, a deceiver, by necessity.”

Mr. Dotrice appeared in more than 50 plays in London, New York and other cities, not counting some 300 more as a young British repertory stalwart. He performed for nine years with the troupe that became the Royal Shakespeare Company, took scores of roles in television and Hollywood films, and became familiar to millions on television series and mini-series broadcast on both sides of the Atlantic.
