LOS ANGELES, California (AP) -- Distressed by thoughts of war, terrorism and natural disasters? Maybe an uplifting movie will take the edge off. For its ninth annual celebration of cinema, the American Film Institute aims to uncover the "most inspirational films of the century." "When times are darkest, during war and depression, movies ... provide a remarkable way for us to find ourselves again," said Jean Picker Firstenberg, AFI's director and chief executive. "We need to feel good again, and that's how these movies make us feel."
