Like it was mentioned earlier, you could probably get a really bone chilling scene
by leaving the gruesomeness of Joker to your imagination...or from another point of view.
For instance, everybody wants to see joker carve a smile, yeah? But I doubt a PG-13 movie would ACTUALLY show the process. But let's say Joker shoots a man and he falls to the ground. Joker pulls out a knife and begins to slowly carve a smile in the guy's face while he's still alive. A simple solution would be to focus the camera on Joker's face the whole carving, showing how happy this really makes him, while you just hear the man's screams in the background. When it's all over there's a shot of Joker's hands, now very bloody, and a shot
of the finished victim now with a permanent grin.
You get your grin. And , TO ME, that's much more disturbing.
Want to push the envelope more? Let the viewer see the carving from a different perspective. Let's say that man Joker shot, let's say he has a little daughter and she wakes up from her father's screams. She slowly walks towards the living room, and peeks in (the camera only shows HER perspective I mind you) and you just see this twisted clown perched over her screaming father doing something with a knife. Joker then turns around and notices the little girl. Stands up, his hands all bloody, and points his knife towards her, saying "Now...let's put a smile on that face!" He begins to walk towards her and we cut to a different scene.
So Joker basically murdered a father and little girl AND carved a smile in their face, without much blood or gruesome "Hostel" violence. It's kept PG-13
And to me that's more ****ed up.
What do you think?
