Character mistake: USA flags are supposed to be displayed with the Union (blue area) on top left corner, whether it's displayed horizontally or vertically. USA missiles at times displayed the flag backwards. Also, at the end of the movie, the flag hung on the hangar next to the USSR flag is backward. (01:40:57)
Continuity mistake: When we see Dr Bradley in the back seat of the limousine on his way to the meeting, he is wearing a white shirt and a black tie. When he arrives at the meeting room, he is now wearing a black shirt and striped tie.
Dr. Paul Bradley: Why don't you stick a broom up my ass? I can sweep the carpet on the way out.
Trivia: The avalanche scene, where a "splinter" that hit the Swiss Alps causes the avalanche consists of stock footage from the made-for-TV movie Avalanche, which made its debut a year earlier. (00:59:20 - 01:01:20)
