Los Angeles, CA -- What has four legs, but can't walk, yet still follows Clint Eastwood around? An empty chair. Three weeks after he used an empty chair to represent President Obama at the Republican National convention, Eastwood walked past 16 empty chairs on the green carpet for his new movie "Trouble With the Curve." They were unfilled bleacher seats. When they were pointed out to him, Eastwood obviously got the joke. He laughed and said "Oh my God, yes."
