The helicopter fly-in scene
Did Sir Maurice fly the helicopter himself, or was there a pilot who just wasn't shown?
It swooped in so low and dramatically as it was landing on the estate grounds as if purposefully making some kind of personality statement about the pilot, which would have fit with Maurice's character. And it looked like it was just a two-seater, which would only have left room for Sir Maurice and his wife.
But on the other hand, they seemed like the type of people who would be chauffered everywhere, including in the air.
(I hesitate to even post this since it seems no one may read it. There was only one post in all of 2013 on this board.)
