In 1997, George Lucas digitally altered Han Solo's introduction. Rather than shooting Greedo from under the table, Greedo now gets the first shot -- misses -- then Han fires back. That additional blaster shot sparked a war between Lucas and the fans that would change the course of movie fandom. With Jonathan V. Last, Annalee Newitz, Chris Taylor and Josh Gilliland of "The Legal Geeks." This is part IV of a V part series on the cultural legacy of Star Wars.
