Horne was responsible, in a different way, for helping to create one other great movie. Her granddaughter, Jenny Lumet, wrote the tender, incisive script for "Rachel Getting Married." The screenplay became a tumultuously moving film about a recovering addict (Anne Hathaway) who gets a weekend pass to attend her sister's wedding. The movie has an electric, musical temperament; it sets off emotional vibrations that are encompassing, delicate and sure. And the action unfolds in an unselfconscious racially-mixed world.
