Not being able to talk has been a good and bad thing. It's good because you get to concentrate on the finer details of acting. You get to concentrate on movements instead of worrying about what you are going to say. The way that it is bad is that it makes it hard to communicate exactly what you are doing. Just like the one exercise where one person goes up and starts doing an activity and others join in. There were times where people didn't know what's going on and they changed the scene.
