The original film did not really "Americanize" the story. They purposely filmed in Germany not only because it was cheaper, but because director Mel Stuart liked the "ambiguity" of the location. Stuart liked the idea of the location being a place that would not be easily pinpointed by many, giving the film a fairy tale quality and the sense that it does not take place in any particular place or era. He felt that would give the film a "timelessness", and it appears he was correct.
Also, Dahl did not like the changes made to his screenplay which basically plopped his children's book into screenplay format. As written, the movie would have been over 2 hours long, and it had no villain, which everyone felt was a necessity. Thus the creation of the Slugworth character. Also, Dahl's screenplay ended with Grandpa Joe yelling "Whoopee!", which everyone thought was a weak ending. Director Stuart stopped the filming of the final scene and was able to find writer David Seltzer who was vacationing somewhere in Maine. He told Seltzer he had to come up with a better final line for the film, and he did; right there on the phone. He told Stuart that Wonka should warn Charlie to not forget what happened to the man who suddenly got everything he always wanted. To which Charlie asks, What happened? ANd of course, Wonka's response, "He lived happily ever after." Stuart shouted "Perfect!", slammed down the phone and filmed it. Seltzer really was the person (along with Wilder and set designer Harper Goff) who added a touch of magic to the story. It is hard to believe the film would have become the classic it has without his involvement in sharpening and improving the story.
There are two great books about the making of the film, PURE IMAGINATION: The Story of Willy Wonka and the Chocolate Factory and I Want It Now!: A Memoir of Life on the Set of Willy Wonka and the Chocolate Factory by Julie Dawn Cole.
