I must say, these movies have a lot more color. :) Having a love of lists and recommendations myself, I thought the AFI choices wouldn't be a bad idea. There are a lot of Academy Award winners here, as well as popular classics like Star Wars, Indiana Jones, Snow White and stuff like that. Well, well...off you go. ;)
