Budding lawyers are told to watch movies like this for ideas, and actors spend time in court doing the same thing . The trick for lawyers is to make it real. Hackman does and then some. His theatric posturing may leave some people cold, but he wins big money for "the little guy.". However, he opts not to have anything to do with the clients later. His daughter not only notices this flaw, but he cheated on his mom, and was rarely home. The point is, the movie is a lesson not to take baggage like grudges to court and to win your case by unencumbered, solid arguments. The prosecution or the defense are always looking for ways to make their opposition lose focus.
