From J. W. Rinzler Blog:
“During a business trip to New York City a week later, I went to a movie theater to watch [Attack of the Clones] again. I wanted to see how people were reacting to it. During the climax, when tall Dooku turned to see who had dared enter his hideout—and saw small Yoda, who pulls out his lightsaber before launching into their peripatetic fight—the audience cheered.”
