He said, "David and I started developing ideas for that almost immediately. We were receiving input from really anyone. Sam Taylor-Johnson, the director of the film, would come in every couple of days and see where we were headed with one idea or another and give us guidance."

"The thing that I think made it such a challenging set was because it's not a normal environment... There's some level of understanding of what that space is and does and should look like. With the Red Room, it's just so out there and fantastical that it was hard to ground it make sure that it felt real."
