George Macready was an American stage, film and television actor whose career spanned nearly 30 years.  He graduated from Brown University and worked briefly as a newspaperman in New York.  Attracted to the theater, on the advice of the Polish classical stage director Richard Boleslawski, Macready pursued an acting career.  Later, he claimed a common lineage with the 19th century Shakespearean thespian, William Macready.  His distinctive to-the-manor born diction, refined features, aristocratic bearing and prominent scar on his right cheek were affects well-suited to playing urbane but vaguely sinister characters.

Macready made his Broadway debut in 1926 in "The Scarlet Letter."  He continued to work on Broadway until 1958, appearing in 15 plays—mostly in dramatic roles, but also making some comedic turns.  Macready's first film credit was playing a schoolteacher in the 1942 World War II drama, "Commandos Strike at Dawn."  He appeared in numerous films, including "The Seventh Cross" and "The Missing Juror"(both in 1944), "Counter-Attack" and "My Name Is Julia Ross" (both in 1945).  His best role during the 1940's was the mysterious and malevolent Ballin Mundson in "Gilda" (1946), starring Rita Hayworth and Glenn Ford.

Beginning in 1954, Macready appeared in numerous television series, ranging from westerns to crime and science fiction genres.  He made two appearances on THE RIFLEMAN, portraying Judge Zephonias Burton in "Eight Hours to Die" (episode 6) and Matt Wymerman in "Lariat" (episode 67).  His performance in Stanley Kubrick's "Paths of Glory" (1947), in which he plays French General Paul Mireau, is regarded as Macready's best work.   The film is a semi-fictionalized account of military brutality and mutiny in the French Army during World War I .
