Rosa Parks was originally drawn as one of the protesters at the courthouse. But she was deleted due to her death just weeks before the air date. Parks can be seen briefly in the background at the celebration in front of the courthouse.
Huey's speech at the courthouse was the script given to actors who auditioned for the role of Huey.
The line near the end of the episode in which Huey narrates "...Vexed. Yeah, vexed is a good word." is based off a line from Lord Chronos in Justice League Unlimited in the episode "The Once and Future Thing: Part 2"
When Huey and Tom meet at the courthouse, a man wearing a baseball cap and backpack is seen walking by. This man is based on producer Carl Jones
