Corrected entry: In the scene where they are reprogramming the laser in the B1 bomber, Laslo enters the coordinates of 34 degrees, 10 minutes 15.21 seconds north latitude, 119 degrees, 7 minutes west longitude. I checked these coordinates at http://itouchmap.com/latlong.html and there is nothing there but woods. I checked the whole west latitude area from 7 min to 8 min and Dr. Hathaway's house (nor any other house or development) is anywhere in the area.
Corrected entry: At the end when Dr. Hathaway's house gets the popcorn treatment, they are shown flying around in an Air Force B-1 bomber - a B-1 bomber doesn't have an interior like the one they showed, that was from an Aircraft Warning and Control (AWAC) plane. Not to mention that the Air Force didn't start using the B-1 until 1986 and the movie took place in 1985.
Corrected entry: Mitch states to Jordan that he can not start peeing when she asks him in the rest room scene, however we can see in the mirror reflection as she enters that he is peeing.
Corrected entry: The monumental cost of buying billions upon billions of popcorn kernels would be out of the realm of poor college students.
Corrected entry: In the scene where Chris removes a frozen cylinder from the freezer to make a "coin" for the vending machine, the characters refer to it as "liquid nitrogen". This cannot be true. It is a solid and not a liquid. Second, liquid nitrogen exists at -160 C, and cannot exist as a solid except under high pressure. Anything stored in the freezer would not remain solid indefinitely unless its melting point is above minus 20 C. Finally, even if it was liquid or solid nitrogen or even dry ice, Chris would not be able to touch without severe injury to his fingers.
Corrected entry: After Chris Knight has his epiphany on making the super laser workable, he holds a meeting and explains, in very technical language, how it's supposed to work. The explanation he gives is true, but meaningless, since it's essentially a generic explanation of how all lasers work, shedding no light on his particular innovation.
