Factual error: Lt. Harp is told by Capt. Leo that the Lieutenant has 56,000h of UAV flying time, That is ridiculous. Even seasoned pilots of the Military Airlift Command do not have that many hours. Drone pilots can fly up to 1,800 hours a year, and Harp hasn't been flying drones for 31 years straight.

Continuity mistake: In the desert digging, the Nova's trunk is open, then shut. (01:42:00 - 01:45:00)
Revealing mistake: When "Snowball" is sleeping on Lena's bed, it is obviously a "stuffed double" (stand-in). Snowball is usually partially hidden behind the dog (so breathing doesn't need to be shown/mimicked). The failure of Snowball to make even a slight movement is a giveaway (e.g, no ear movement when Lena starts talking), but even the stuffed lion, in itself, is not a very good replica - it simply looks fake.

Continuity mistake: Nicolas Cage is handcuffed behind his back by a state trooper, but then there is a rope tied around his hands, not handcuffs, and he frees himself by breaking the rope. (01:01:46 - 01:06:45)
Continuity mistake: When Jang and Tiger are talking at the poker game, Jang points a gun at Tiger and is the gun seen pressing against Tiger's forehead. In the next shot, the gun is suddenly a few inches away from Tiger's forehead. (00:18:40)
