Maggie Smith
One of the most revered actresses on both sides of the Atlantic, Maggie Smith created a gallery of indelible characters on stage and screen, which ran the gamut from repressed spinsters to comical eccentrics. Smith quickly became an actress of note with performances in several Shakespeare plays before making an auspicious feature debut in "Nowhere to Go" (1959), before stealing the show in "The VIPs" (1963) and gaining international acclaim for her Oscar-winning performance in "The Prime of Miss Jean Brodie" (1969). While making her name in dramatic roles, Smith proved equally adept at comedy, particularly with a standout turn as a sophisticated sleuth among an all-star cast in "Murder by Death" (1976). She earned another Academy Award for her brilliant portrayal of a crumbling actress in "California Suite" (1978) before transitioning to a repressed spinster in "A Room with a View" (1986). Though she appeared in a supporting capacity in broad Hollywood movies like "Hook" (1991) and "Sister Act" (1992), Smith found comfort on Broadway and London stages while continuing to earn acclaim for smaller films like "Tea with Mussolini" (1998) and Robert Altman's "Gosford Park" (2001). Smith reached her widest audience with "Harry Potter and the Sorcerer's Stone" (2001) and its numerous sequels, and earned critical acclaim as Dowager Countess of Grantham on the wildly popular series "Downton Abbey" (ITV/PBS, 2010-16), allowing her the opportunity to impress a whole new generation as she continued to maintain her reputation as one of the greatest actresses of all time.
