“Animation came in for a number of reasons. There were certain moments that weren’t on film, especially the trial. We needed a way to show what was happening in the courtroom. We could have done it in renactments, or though talking heads, or we could have had courtroom drawings panned and scanned.

“But I thought animation would have served as commentary on the trial; Jerry Rubin called it a `cartoon show,’ and when I read that quote, the bells went off.” — Director Brett Morgen talking to John Anderson in the N.Y. Times about his long-in-preparation, partially animated documentary Chicago 10, which will open the 2007 Sundance Film Festival.
