Ah ok. So an example would be - Spielberg adapting Jurassic Park into an extremely successful film, then, the Crichton estate would only approve Uni creating a theme park if there were to be no involvement from Spielberg, but, the park uses John Williams' scores and the same art direction and sets?
I hope this doesn’t happen, when Guillermo del Toro initially stood in for the directing position of the 2nd Middle Earth trilogy people weren’t happy- now that Jackson has created 6 films in Middle Earth; people associate them to each other and I can’t see the fans happy without PJ aboard the project.
