If you're a film lover, you'll probably want to take a look at this site I found while researching an information request a while ago. American Rhetoric is the name of the site. It's a large database containing historical and contemporary speeches on a variety of topics. The question I worked on was of a political nature, and I spent most of my time searching speeches given by contemporary political figures.
Once I was done with the question and had more time to really explore the site, I found another gem of a feature. In addition to political speeches, American Rhetoric houses an impressive collection of speeches from films! I'm not talking about only a few films. The movie speech database contains over 200 speeches. If it was an American film with a prominent speech, it's probably on this site. The really cool part is that many of these speeches are presented with text, photos, and audio/video. Go get caught up in the rhetoric!
