Local Hero, Rush Hour seems like classic FOOW stories.
Star Wars, Lord of the Rings and Transformers also because the protagonist is thrown into a world he doesn't understand (wamp rats not withstanding).
What about Good Will Hunting? Isn't part of Will's conflict driven by the clash between the two worlds he strides?
Or Silence of the Lambs where the alien world Clarice is trying to understand is actually Lecter's and Buffalo Bill's mind?
