Revealing mistake: In most of the scenes of the film, the famous filly is impersonated by a colt.
Revealing mistake: When Kale and his father are hit by the red truck at the beginning of the movie, a rectangular hole can be seen in the trunk where the spare tire is, obviously not for the tyre itself or made by the crash. (00:04:25)
Revealing mistake: During the long tracking shot at Dunkirk, steadicam operator Peter Robertson had a little assistance in getting around. This took the form of a kind of golf cart (from the beginning to just after shooting the horses), and later a rickshaw (from little after the choir to just before the steps ascending the billets). If you look at the ground to the left just as the camera begins backing away from the carousel, you can see tracks in the sand made by the rickshaw. Keep watching the sand near the actors' feet to see more.
Revealing mistake: When Joseph goes to pick up the prisoner, there's a close-up of the paperwork; the prop is something recycled, or perhaps a real prison movement slip with Alex Veadov's picture stapled on, because the character's name is Vadim Nezhinski, a white Russian, but the documents say "Anderson, Robert", with a B (Black) for race. (01:09:45)
Revealing mistake: The protagonists just had sex. The lifeline operator chats with him through MSN; notice how the timestamps of the messages do not match at all the time that supposedly elapses, going from 12:56 to 01:00 all of a sudden and even jumping from 01:01 to 01:50.
Revealing mistake: An obvious double for Anne Archer the morning after her assault. The double's hair isn't shoulder long and is thicker than Archer's.
Revealing mistake: When the boy accidentally shot himself, the gun wasn't pointed in the right direction at all.
Revealing mistake: At the start when the tree falls through the window, it's been pushed through the window horizontally. Since it does no damage around the window as you would certainly expect from a tree falling through an arc. (00:01:20)
