NEW YORK (AP) _ Playwright Donald Margulies and actress Marian Seldes are the recipients of the 2000 Evans-Kingsley Awards, given each year by the Dramatists Guild, an organization of some of the country's best-known playwrights.

Margulies was awarded the prize for his body of work, which includes such plays as ``Sight Unseen,'' ``The Loman Family Picnic'' and ``What's Wrong with This Picture?'' He won the Pulitzer Prize for drama this year for ``Dinner with Friends,'' a play about marriage and infidelity.

``The theater is my life, and this is one of the most beautiful moments I have ever had,'' an emotional Seldes said Tuesday in accepting her prize.

Seldes, one of the theater's most beloved actresses, won a Tony Award in 1967 for her performance in Edward Albee's ``A Delicate Balance.'' In the fall, she will open off-Broadway in Albee's new drama, ``The Play About the Baby.''

During the golden age of Broadway drama, Sidney Kingsley was one of the theater's most successful playwrights. His first big hit was ``Men in White,'' which opened in 1933, and concerned the clash between the conflicts and ideals of a young doctor. His other hits included ``Dead End'' (1935), a realistic tale about rising class differences in New York, and ``The Patriots'' (1943), a drama about democracy and the battle between Thomas Jefferson and Alexander Hamilton, and ``Detective Story'' (1949), which focuses on the death of a policeman.

Madge Evans, Kingsley's wife, was an actress who appeared in many of her husband's plays as well as such movies as ``Dinner at Eight'' and ``David Copperfield.''

The Evans-Kingsley Awards include stipends of $20,000 for each winner.
