I've only noticed this on the TNT airing of this movie. I haven't checked this on VHS format.
When the captain of the guard shoots the young guy who holds the key to Andy's innocence, you hear 3 shots. However, there are 4 bullet holes in the guys back.
It is possible that this was a result of being edited for television.
When Captain Hadley shoots Tommy in the VHS version, there is so much blood, they couldn't show it on TV. So, they cut out the blood and "pointed the camera" somewhere else. That's why it looks so wierd.
No, it's because the second shot (i think it was the second) is so bloody that they couldn't show it on TV, so they left out the sound of the shot and forgot to make it "add up".
i can't say that i saw the version on TNT. I didn't think that there was much blood in the VHS version, but that doesn't mean much.
There are four shots in the VHS version, the version the producers want people to remember. I have heard much contraversy about this. I have heard people who think that there were three, I have heard that there were five.
if you listen carefully, rewind it three times if you need, there are four shots. the sound has been recorded as such:
[bang] -short pause- [bang][bang] -shorter pause- [bang].
four shots.
I also noticed that there were three (or maybe two according to my ears) gunshots and four bulletwounds in his back on the tnt version. When I said something though, my friend that was watching the movie with me said that bullets ricochet within the body. Now I don't know if that is true, but it sounded pretty convincing. Perhaps the gun that Hadley used makes a difference too (was it a shotgun?).
