Heres something I just noticed. I was watching my MGM DVD of T1 and was watching the scene where the Terminator breaks into Sarah and Kyles motel and opens fire. He then goes over to the bathroom and kicks the door in. In the mono version, you can hear the gun firing in the background when it cuts to Kyle and Sarah hijacking the pickup truck. Until now I assumed that sound was a drumroll in the music. Nope it was the gun. How I know and what point Im making with this post is I played the scene again with the 5.1 mix and theres NO sound after Terminator kicks the door in! Interesting huh?
