I didn't memorise it nor do I feel inclined to go looking for it.
But it's James Cameron, so I doubt it was very substantial.
Look, you can't just make up new definitions for words to suit your argument. That is not at all what grounded means.All 3 movies are fictional but GOTG is not grounded as the other 2. Grounded means actually telling a story and being more self aware. Dark Phoenix could be more Interstellar and less GOTG,as a grounded movie or the Martian, which was made by Fox ...
Definition of grounded
: mentally and emotionally stable : admirably sensible, realistic, and unpretentious remains grounded despite all the praise and attention
...because somebody watched his latest two Alien movies and wouldn't let him.making me to ask why didn't Ridley Scott direct this movie.
Okay, real answer: because Ridley 'I have no integrity' Scott is already busy making one of his progressively worse alien sequels/prequels.
