As Master Chief O'Malley (David Keith) leads Lt. Burnett to see Admiral Reigart, Burnett asks him if he caught the University of Tennessee's football game loss the previous Saturday. O'Malley replied, "I don't know anything about that." David Keith graduated from the University of Tennessee.
This is the first movie to feature the US Navy's new F/A-18E/F Super Hornet.
The film is based loosely on the experiences of USAF Captain Scott O'Grady, who was shot down over Bosnia. O'Grady brought a lawsuit down on 20th Century Fox for damages to his character. He claims he didn't curse as much and never disobeyed orders.
In the football scene, the filmmakers actually tried to have the catapult shuttle kick the football off. Unfortunately, the shuttle completely obliterated the ball, forcing a Navy Master Chief to just chuck the ball in the air for the desired shot.
The US Navy Ship used is the USS Carl Vinson (CVN 70) which has been used in several other films.
Lt. Burnett's call sign is "Longhorn". Stackhouse's is "Smoke".
British news channel Sky News features prominently in the film. Sky News and 20th Century Fox (the studio that produced the movie) are both owned by Rupert Murdoch's News Corporation.
During the period while filming, was the first time in 104 years that Slovakia did not get snow, so all the snow seen in the film was created by special effects.
Director John Moore was nearly killed in the scene where the tank busts through the wall. He was pulled away by a stuntman just in time.
The French paratroopers pictured in the movie actually wear their berets the wrong way around. French red-berets are the only troops, along with the Marine "fusiliers commandos" (green-berets) to wear the beret insignia on their right, whereas the ones depicted in the movie wear it on the left.
