Partly, because there's a German DVD available that features some kind of an extended cut with nearly all the deleted scenes reinserted that can be found on the US-Laserdisc or US-DVD plus two scenes that are not featured amongst the deleted scenes of the US-DVD. A detailed comparison with pictures between the normal R-Rated version and this special cut can be found here.
The werewolves barricade themselves in the barn to get away from Chris and his silver bullets. He and Karen then set fire to the barn and run for the car. They pass Sheriff Sam Newfield (Slim Pickens) on the road and stop to give him a lift, but he begins to turn into a werewolf and shoots out their tires. Chris shoots Sam, and they take his patrol car. Before they can get the engine started, they are swamped from all sides by more werewolves. One of them breaks the rear window, hops into the back seat, and bites Karen on the shoulder before she is able to shoot him with a silver bullet. They finally get the car going, Karen looks in the back seat and sees that the werewolf she killed was her husband Bill. Sobbing, Karen says, 'We have to warn people, Chris. We have to make them believe.' The next scene shows Karen returning to her position as news anchor. Instead of reading the scripted report, she begins to talk about her experience at the Colony. As she nears the end of her speech, she gives visual proof by turning herself into a werewolf after which Chris shoots her. Of those in the viewing audience, some think it's special effects but one man in a bar claims it was real. The camera then pans down the bar, and Marsha can be seen seated there, waiting for her hamburger to cook.
