A great movie monologue is a hard cinematic element to create. You need to find the perfect place to insert your scene, whilst making sure that the dialogue of your piece isn't too preachy and that the actor who performs it is competent. Throughout cinematic history there have been hundreds of attempts to create movie monologues.
Quint's speech toward the end of Stephen Spielberg's classic action adventure is so infamous that it has gone down in cinematic folklore. Much has been made about which member of the "Jaws" team created this exchange with John Millius, Robert Shaw, and Carl Gottlieb; each saying that they had a hand in it. Quint tells Brody and Hooper about his time on the USS Indianapolis which sank after delivering the atom bomb. Shaw's performance is perfect as well as immensely heartbreaking, and then the big shark had to come in and ruin it all.
"The Great Dictator"
Charlie Chaplin is mostly remembered for being the greatest silent movie star of the early 1900s. But he also made some talkies with "The Great Dictator" being his last great film before all of America began to think he was a commie. It also features Chaplin's most heartfelt cinematic speech which includes the following: "Our knowledge has made us cynical, our cleverness, hard and unkind. We think too much and feel too little. More than machinery we need humanity. More than cleverness, we need kindness and gentleness." A great monologue like this still rings true to this day. If only Chaplin had talked a little bit more.
George C. Scott truly embodied the character of George S. Patton, and his rousing speech at the opening of the movie sees Scott at his impetuous best. With his crackly voice and mannerisms, Scott was able to land that year's Best Actor Oscar for his performance. Studio execs thought that the image of Scott's Patton standing before a large American flag was too strange of an opening and fired Francis Ford Coppola from the piece because of it. Clearly a huge mistake as Coppola would also win the Best Original Screenplay Academy Award later in the year too.
