I love foreign posters for American movies. The artwork is usually more interesting. The text is in another language. And it gives you a familiar-but-not-quite feeling.
Escape to Witch Mountain was one of my favorite movies growing up. That's why I tracked down a copy of the Italian version of its poster. MovieGoods is selling the Belgian version (pictured above) for $19.99 and it's almost as cool as the one I own. Buy it.
