Regarding length of time on location, I agree that it is somewhat correlated to length of scene in the movie. But scenes involving stunts and practical effects likely will take longer to shoot because of all the setup and precautions. So use of locations involving fight scenes (such as at Greenwich University) are going to be overrepresented compared to their screen time in the final film.
A very good point American Maid, and thanks to you and Elizah72 for letting me know about the Stonehenge. I am glad it will be appearing in the movie.
