At the end when Mike is standing in the corner and Josh is supposedly dead and you can hear Heather screaming in the background (the distant background, like in another room of the house) someone picks up the other camera, who IS taping? I was just wondering. Watch it again and you'll see what I mean. It's weird.
Only the camcorder had built-in sound, film cameras do not (Mike was the sound guy, remember)? Once things got really bad Mike didn't bother recording the sound anymore so the soundtrack comes only from the video camera. In that scene at the end, Heather is using the B&W film camera but the audio accompanying it is coming from the camcorder still running on the ground (and away from the film camera) That's why it looks/sounds weird.
The sound is coming from the camcorder Mike was holding, which ends up with him in the basement. Heather is holding the film camera, which does not have sound. This is why even though you are watching from Heather's perspective at the end of the movie, her screams sound muffled until she gets to the basement (as that's where the sound is being recorded).
This is intentional, and probably the most dramatic effect in the movie, and what really sells it.
Call me a wuss, but this movie scared the sh*t out of me. [this coming from a 16 year old girl that plays Resident Evil, Silent Hill, and watches any scary movie she can get her hands on]
I just want to say, How can you hear the sound that Mike was recording, when you are seeing the film that Heather was taping? If you were hearing her screams getting louder, wouldn't you have to be watching the color tape? You can't hear the recorded sounds unless you are WATCHING the color tape.
Yes, the camera that Heather was carrying was film and did not record sound. More than likely, the sound (Heather's screams) are being recorded on the DAT Mike carried for the entire movie.
A lot of people have talked about the way the film is edited, but I remember all the promotions surrounding this film, and they specifically said they were showing the footage in its entirety, which means it's completely unedited. For Heather to be filmed from behind as she's running to the basement made no sense. There was only one camera left, and she didn't even have it with her anyway. It was in the basement.
I saw this for the 1st time last night- my friend had a theory that at this point the camera was taken by the killer + it was in fact the killer who dropped the camera
