One big change that I made [from the book], which at the end I felt was better, was [taking out] the mother figure – the person who was narrating, in a way. It felt to me that this story would feel more powerful if it was from Ferdinand’s point of view, and also with Ferdinand to be living in this macho world – in a world where it’s all about bulls. It’s all about being strong, or being a fighting bull. It gave more contrast to him not wanting to be part of that.
