The opening scene
How did the director make the dogs look like they were really fighting - or were they really fighting???
I want to know this too. The way it's filmed you don't see any real violence, just the dogs struggling while covered in blood. I'd like to believe it was faked, but you never know with some films. If it was a Peckinpah film there would be a good chance it would be real.
