Mary Tyler Moore, 'Ordinary People' (1980)
Moore first made a name for herself in the 1960s on The Dick Van Dyke Show — playing Laura Petrie and breaking the glass ceiling regarding the wearing of capri pants on TV. She became an even bigger part of television history as the star of her own sitcom, The Mary Tyler Moore Show, one of the first shows to reflect the Women's Movement of the 1970s. But you would certainly never expect her closed-off WASP of a mother in Robert Redford's 1980 directorial debut, Ordinary People, to exclaim "Oh, Rob!" or throw her hat in the air. This tragedy about an affluent family trying to recover from the death of a child won four Oscars, including Best Director for Redford and Best Picture; Moore's serious-as-a-heart-attack performance garnered her a Best Actress nomination, though she lost to Sissy Spacek (for Coal Miner's Daughter).
