Hollywood movies dealing with the law and closing arguments tend to dramatize the main emotional themes. However, creating a theme to "kill" in a closing argument should be the goal of every lawyer in any case.
Finally, if you are ever called to jury duty, and hear the closing argument, perhaps you’ll close your eyes and picture Jake Brigance or Atticus Finch delivering their last lines to the jury. But remember, separate Hollywood from the real world and keep an open mind to facts of each case.
