The phrase, "Big Brother is watching" was never spoken in the book, but it was plastered on posters everywhere.
On a side note, my searches reveal you have yet to cover a Bond flick. No doubt, you have this planned out to some extent (well, knowing you, months in advance
), but might I recommend
Skyfall, released in 2012? It was my first Bond, and is still my favourite, and really has a good plot. I think it was made for you to critique.
