I just thought of one of the most unbeliveable ones! IN T2 when the truck is chasing the motorcycle with the kid on it and he bumps the kid but he doesn't fall, Yeah Right!!! Also same movie go rent it, and watch when the truck comes off the overpass in slow motion the windshield falls out... but a few seconds later it is perfect until Arnie shoots it, it shatters and the driver pushes it out! also watch the dents on the truck appear and then disappear, you think they used about ten trucks in this chase? Funny Huh!
