The children mentioned in the headline of the Queen's newspaper were presumably abducted in the night by the other giants. None of them were found during the military incursion into Giant Country. The other giants have neither the temperament nor the intelligence to keep prisoners. Those kids were eaten. This is made more explicit in the books: the giants eat eighteen girls and fourteen boys between them and leave their bones under the windows.
The Giant Country (in the 2016 film) is littered with wrecked cars, trucks and even a railway carriage. Why would the giants bother bringing them back unless they had people in them?
Perhaps it comes under the heading of the giants being general scavengers, and picking up anything they can find, including whole churches.
The BFG's breakfast at Buckingham Palace. At first they reason that as he is four times as tall as a six-foot human, his breakfast should be four times as large – but he eats the whole lot all at once, says that all that food was just "one titchy little bite", and asks for more. Of course, the BFG isn't just four times the height of a human: he's four times as large in all three dimensions, meaning that they ought to have multiplied the size of his breakfast by 64, i.e. four cubed. Dahl was no stranger to the concept; in George's Marvellous Medicine, he noted the difference between a living thing growing in all directions as opposed to simply growing taller.
Many of the dream bottles end with the dreamer waking up and being told breakfast is ready. Wouldn't that not be a part of the dream itself? It absolutely can be; ever have dreams where you wake up, start going through your morning routine, and then wake up for real? There you go.
The giant’s fear of rain is justified- not only does their size make them prime targets for lightning strikes, the weight of the rain would slow them down!
In the illustrations, the BFG has light skin while the other giants have burnt brown skin. Well, of course they do; the other giants lounge around in the sun all day before going out at night for their meals, while the BFG stays in his cave to avoid them and only comes out at night to dream-hunt.
