The boy playing Thomas is really good... Days is lucky to have found him, and bless his parents for letting him do this. It is difficult as a parent has to be on set, plus another person who keeps watch on the child's welfare, plus a teacher. (It's why we don't SEE the kids that often, and of course, why doll in blanket is sooooo popular). And.......as Jason D. showed us so well, we also get the invisible Jude's crying voice.
