You think Disney would miss out on the chance to promote their upcoming movie??? Nope... don't think so.
There is a little more than this sign though. There's a little "carnival games" area where you can throw rings around giant plastic Coke bottles, look into some funhouse mirrors, do a bean bag toss (and get a promo button just for participating), and take pictures in front of an Oz backdrop. So pass on through when heading towards World Showcase.
