Leigh Whannell explained how he conceived the werewolf's point-of-view shots, saying: "I had this idea of the camera moving around the room and suddenly what seemed like gibberish became legible, and you realized there was some invisible wall that the camera had crossed through. I started researching wolves, how they see, the colors of their eyes. I was thinking about how animals hear. When we talk to our dogs, we all anthropomorphize our pets. I have whole conversations with my dog where I'm like, "What are you doing? Oh, you're upset. What are you upset about?" You know that he's just staring at you. They recognize tone and maybe up to 20 words. I was thinking about that. This classic Wolf Man story is a great way to use this because usually in Wolf Man stories, the transformation is very quick. I was like, what if you slowed this down and treated it more like a degenerative illness? I was thinking more of a film like "Still Alice."
