The footage of Mr. Bale’s attempted visit is dramatic. In it, he is seen pleading with the men who guard Dongshigu’s entry points and then retreating as they push and punch him. “Why can I not visit this free man?” he asks repeatedly. The men, dressed in thick green winter coats respond with shouts of “Go away.” Even after they have retreated into their car, the group, which included a translator, was chased for 40 minutes by men in a gray van.

“What I really wanted to do was to meet the man, shake his hand and say what an inspiration he is,” Mr. Bale said.
