Factual error: Ashley Judd is convicted of murdering her husband for the insurance money and that would make it a first degree murder charge (first degree meaning she planned the murder). Because of that there is no way she would have been eligible for parole after just 6 or 7 years.
Continuity mistake: Terence Stamp takes out a pursuing vehicle by reversing his own car into it at high speed and pushing it over a cliff. When he subsequently drives off, amazingly there's no damage at all to the rear of his car. Shortly before, it is peppered with gunshot holes which mysteriously disappear.
Other mistake: During the scene where the Japanese are being rounded up and taken to the internment camp, the camera is panning over the crowds of people walking down the street. Half way through this scene, there is a woman and a little girl, who seems to be carrying a stuffed Elmo, hardly appropriate for the time period.
Factual error: When Suzanna and Lisa are at Daisy's house, Daisy lays out money for Lisa so that she can get pancakes, and the bill she laid down is one of the new bills. This movie is set in the 60s so of course they wouldn't have the new bills, considering they didn't start making them until 1998.
Visible crew/equipment: In a scene not too long after Tom Cruise attempts to revive a hooker who has OD'd, he is speaking with an older gentleman. The three are in a bathroom and the hooker is passed out on a chair. One of the shower or light fixtures toward the left of the screen is shiny, and in a shot during which the camera briefly tracks in reverse, you can see the camera, cameraman and the focus puller reflected. It's pretty clear and not all that fast.
Deliberate mistake: When Tarzan fights with the leopard, it scratches his chest. However after they fall into the pit and Tarzan comes out carrying the dead leopard, the scratches on his chest have amazingly healed. [It is a long-standing Disney tradition that no evidence of violence is shown on screen. Still a mistake, but there's why].
