In Arnie's world, however, bones (and other miscellanea) reflect the x-rays back to the scope, allowing the assassin to see his victim's skeleton through walls. The only place for our heroes to hide is behind the refrigerator, kryptonite for super assassins with x-ray scopes, as our movie-makers would have us believe.
We haven't even mentioned the ludicrous scene of Arnie hanging out the door of a jet aircraft with one hand as he reaches for a parachute, which is then thrown overboard. He nearly hits the jet's engine when he finally lets go, defying laws of gravity and projectile motion not to mention common sense. And why would he wait seven seconds before following the parachute? We suspect this movie could well become a classic of insultingly stupid movie physics.
