O'Hara was brought to Hollywood as a teenager in 1939 by the great Charles Laughton, to whom she was under contract, to costar with him in the classic film The Hunchback of Notre Dame. She has appeared in many other classics, including How Green Was My Valley, Rio Grande, The Quiet Man, and Miracle on 34th Street. She recalls intimate memories of working with the actors and directors of Hollywood's Golden Age, including Laughton, Alfred Hitchcock, Tyrone Power, James Stewart, Henry Fonda, and John Candy. With characteristic frankness, she describes her tense relationship with the mercurial director John Ford, with whom she made five films, and her close lifelong friendship with her frequent costar John Wayne. Successful in her career, O'Hara was less lucky in love until she met aviation pioneer Brigadier General Charles F. Blair, the great love of her life, who died in a mysterious plane crash ten years after their marriage.

Candid and revealing, 'Tis Herself is an autobiography as witty and spirited as its author.
