Deliberate mistake: When Kate Barlow shoots the Sheriff, she shoots him between the eyes, but when she kisses him there is no hole or anything on his face.
Deliberate mistake: When the two Confederate and Union soldiers meet across the river and trade coffee/tobacco, you can see the other side of the bank behind them. It looks at least 50 feet away, yet before they were able to talk to each other without shouting. Also, the Union soldier raises the pipe to his mouth in his right hand, which switches to his left in the next shot. There is also a mist present at the beginning and end of the meeting, but not in the middle. (00:37:55)
Deliberate mistake: After Emily talks to inspector Girotti she starts a record player. Then she walks over to the window, sees Werner in the garden, and decides to go down. Between shots she appears behind him, which is wrong, as the song from the record goes on, but it's most probably intended. (00:30:45)
Deliberate mistake: When the teacher walks over the floor towards the blackboard, he walks through a lot of blood. However when it cuts, he leaves no traces of blood where he steps.
Deliberate mistake: In the final race of the film, Seabiscuit performs a flying lead change at the gallop while crossing the finish line, in the famous shot taken underneath his neck. Horses normally only switch their leads around turns while racing; it's something done to relieve pressure on the leading foot. From taking the shot over and over again, the horse playing Seabiscuit was probably tired out and a little tender and began to perform lead changes in other places in an attempt to be more comfortable.
Deliberate mistake: When Brian and Bilkins are at the demolition derby, Roman wins and gets out of his car. As he scans the crowd, he sees Brian. When we see Brian the logo on his shirt has a 3D effect to it that goes back and to the left. In all other shots of that logo, the effect goes back and to the right. This shot is reversed.
Deliberate mistake: Instead of being a specific language, Edward has an English to Asian dictionary. I've heard this was done to prevent a particular time period from being established. (01:12:55)
Deliberate mistake: In the scene where Bob and Charlotte first glance at each other in the elevator, the film has been reversed. 3 mistakes are visible. The first one is that the woman's Kimono is reversed, left side tucked into the right. All Japanese garments are always tucked in right side first. Only on the day of your funeral is the left side tucked in first. The second mistake is the lapel hole on Bob's jacket; it is shown on his right. The lapel hole is almost always on the left side of a men's suit or sport jacket. And in every other scene in the film, his lapel hole is on his left. The third is the birthmark by the ear and the 1 inch vertical scar on Bill Murray's cheek are shown on his right side. When in actuality, they are on the left side of his face. (00:08:00 - 00:08:35)
Deliberate mistake: The investigator on his way to Garner, IN, is actually driving along Interstate I-10 somewhere between Louisiana and Florida. The shot of the freeway sign for "Gardner" is from off I-10 in the Florida panhandle and represents Gardner, Florida. The scene shot in Gardner, IN in front of Rachel Weiss' mother's home depicts the Crescent City Connection bridge in New Orleans. This scene is actually shot in Gretna, LA, on the West Bank of the Mississippi, just across from New Orleans.
