There were places Beasts couldn't go
If you've seen the Fantastic Beasts trailers, you know that Newt's suitcase -- luggage that gives Mary Poppins a run for her money -- is his life. In the movie, Newt can walk through his bag into a multi-room zoo and laboratory. The original plan was even more expansive. "As we developed it conceptually, I was really excited about making it trippy and extraordinary," Yates says. "At one point, I got a concept artist to create landscapes in there that were like little universes. They're all completely bonkers... Basically, he had Narnia in his case."
According to Yates, J.K. Rowling wasn't so keen on the idea. "There was one moment when Newt got on a boat and crossed this huge, vast ocean within the case. And Jo said, 'Look, it looks fabulous, but guys, he has to create this with the level of his magic,' and the level of Newt Scamander's magic is home-grown. She said he's got to be Heath Robinson, he's got to sort of knock it together himself. It had to feel much realer. So, out went this sort of multi-dimensional other universe space, and it kind of crushed down to a shed."
