I had never played a real-life character. All the characters that I'd played before were fictitious. So I'd spent all this time creating the affectations and amassing all of the attributes and characteristics and mannerisms, and then Jackie came to the set the first day of filming. I kicked everyone else out of my trailer, and we started to talk. He told me, in his own words, just for him and I, what the whole story was about for him and what that trial meant to him. After that meeting, all of the work that had gone into building the mannerisms and attributes seemed secondary. The most important element was to understand and believe in his cause.
