Continuity mistake: Just before Demi Moore is about to get her head shaved she sees the base commander about equal treatment, and we notice very visibly that O'Neil has one side of her face bruised and all red and swollen. But in the next scene, which takes place moments later, when O'Neil is shaving her head, her injuries are all gone. Where did they all go to?
Continuity mistake: During a training session, Jordan forms a human ladder with another trainee to get her team over an obstacle. The Master Chief is watching this scene through a night-vision scope on his rifle. His line of sight is initially level, then suddenly alters to show the view from a lower perspective.Christoph Galuschka
Revealing mistake: Towards the end of the film, a Cobra helicopter is flying in to assist with the extraction of the Navy Seals. There is a three-quarter frontal shot of the helicopter, one bank of rocket tubes can be seen to be empty; a few moments later, it's firing rockets from banks on both sides.
Trivia: Throughout the film, Master Chief John James Urgayle, played by Viggo Mortensen, reads and quotes poetry. In real life, Viggo is very fond of poetry; in addition to being an accomplished poet, skilled actor, artist, painter, and horseback rider, he published a book of his own poems entitled 'Ten Last Night' before he became well known.Allister Cooper, 2011
Master Chief John Urgayle: Pain is your friend, your ally, it will tell you when you are seriously injured, it will keep you awake and angry, and remind you to finish the job and get the hell home. But you know the best thing about pain?
Lt. Jordan O'Neil: Don't know.
Master Chief John Urgayle: It lets you know you're not dead yet.
