The Inception moviemaker is fiercely protective of his stories and usually bans cast and crew from revealing any plot spoilers.
He is keeping details of his upcoming space drama, starring Matthew MCConaughey and Anne Hathaway, under wraps and he wouldn't even let his regular collaborator Zimmer see a copy of the script.
Zimmer tells British GQ, "All I will say is this: before I began, last January, Chris said to me, 'Hans, I will write one page of text for you. And you will give me just one day. Just write whatever comes to you from this one single page.'
"It (the page) wasn't about the film... in a peculiar way, what Chris wrote down that day, and what he wanted from me, had more to do with my story than the plot of the movie. He knows how to get under my skin. That's the game we play."
The celebrated movie composer has previously worked with Nolan on his Dark Knight trilogy and Inception.
Interstellar is due for release in November (14).
