O'Brien 

a high official in the Ministry of Love in "1984." He tortured the protagonist, Winston Smith, into submission to the totalitarian "Party." O'Brien was played in the film by Richard Burton; it was Burton's last role.

Winston was struck, as he had been struck before, by the tiredness of O'Brien's face. - George Orwell, "1984"
