Christine was my first go to as well. I've seen a few mute characters in smaller and more indie things. Jason is often times portrayed as non verbal, and in No Evil, they have the mute character use sign language while someone translates/interpretes. I do agree that this is not something my limited writing skills are ready to tackle, but in a way that makes this all the more rewarding. It's a way to really push my limits and try to step outside of my comfort zone.

With selective mutism I've found a shocking amount of people online willing to share their story to a camera, since they aren't in public or have managed to work on it enough to be able to speak. Maybe I should look into more things from people who can't speak at all though, since that gives a better idea of the way they might have to engage with people when they are mute. In general, I suppose more research can never hurt and I've really only touched the surface here.
