Trivia: George Lucas decided to release "Star Wars" in May 1977 instead of the start of the summer movie season (in the 1970s, it was a new concept as the result of the success of "Jaws" in 1975) in June because he wanted kids still in school to talk about it so as to spread word-of-mouth.
Chosen answer: Originally, Han shot Greedo outright. The next releases of the films were altered, the first with Greedo firing roughly a second before Han does, and in the subsequent release, Greedo firing just slightly before Han does. Many fans felt that Han seemingly shooting in self-defence took away from his scoundrel character.
