Other mistake: About half an hour into the film, Schuler and Daniels go down to the level 4 bio-lab. They pass through a number of doors that earlier and later in the film reqire an ID card or hand-print scan to access, but they don't use either on any door. (A security guard seems to usher them through one door, but surely such a high security lab would require positive ID at each entry point).
Other mistake: Before getting on the plane, Col. Daniels has a conversation with General Ford. Ford salutes Daniels, which is incorrect; as the lower ranking officer, Daniels should have saluted first as a sign of respect and protocol.Movie Nut
