It's the Big Friendly Giant! You thought it stood for something else, didn't you? OK, I thought it meant something else until I looked it up on Wikipedia.
The first thing I thought of was the BFG 9000....;-D...
Not in the cinema I think. I value my hearing too much and cinema's these days always have the sound set to pain level.
But yes, once it's released for home viewing I think I am going to watch it. I loved the book when I was a kid.
