Best Characters?

I have a comprehensive list of my favorite characters in film and am planning to make a book based on the subject. Here is the list www.listal.com/list/my-epic-movie-character-list. I'd like suggestions of movies I should watch which have truly memorable characters and the names. Just about any kind of movie is welcome. Thanks!

These are my favorites, mostly thanks to the amazing acting skills of the respective actors. www.listal.com/list/my-top-performances
