One of the many great things about the Web is that people can share their obsessive labors of love with the world. Apparently Steven Hill really digs movie screen titles, which are screen captures of the title screens that appear before every movie. While the interface isn't the greatest (basically click on a letter and scroll WAY down until you find the movie you're looking for), the collection is pretty darned impressive. I looked up a few of my favorite obscure movies and they were there (even "The Adventures of Buckaroo Banzai!)
Check out the collection at Steven Hill's Movie Title Screens Page.
