I've also noticed a bit of "zoom" for the opening credits of The Terminator (still have that on vhs as well).

The Terminator was shot 1.33 with hard matting in-camera, so full-screen 4:3 releases are cropped. If you watch a 35mm print of the trailer open-matte, you will see the black bars of the physical matte box (attached to the camera lens) change size from shot to shot.

I've seen both trailers open-matte, there's stuff like the animated electricity spilling into the black bars, and the shot of Arnie in the police car has the small lens flare of the siren light just barely spilling over into the black area.

There'a a clip of a Derann Super 8 print on YouTube, it's a camcording but you can still see that the shots of Arnold are hard-matted, and the insert shots of his hand are open-matte. http://www.youtube.com/watch?v=BpINxrNE8J4
