"In the same way that my first film appeals to kids with this notion of being shrunk, thrown away by their parents and lost in their own backyard, there’s something appealing in this one for adults," Johnston said. "This is the first R-rated movie I’ve made. And I was committed to making the blood and violence be organic. I didn’t want it overlayed on the movie, which I feel happens with a lot of movies. The main character, Lawrence Talbot, is an extreme case but I think we all have that potential, we all have a dark side within us, a beast waiting for release."
