Prince Maurice went to the Valley of the Dim as being a Hollywood director and asked the locals he wants to make a movie in their mines and also to keep this a secret because he do not extra information to be leaking into the public and the locals accepted the deal because they thought even though it will hurt their economy but they will get paid a lot in the end which will make every thing ok.
