Continuity mistake: After Kevin Kline slices his thumb (finger?) in the kitchen, his wife bandages it. Then, as the earthquake hits, they run outside and you can see that the bandage doubles in size.
Continuity mistake: In a few scenes we see in the background BT Telephone boxes this film is set in the 1960's so why are the boxes new with the new BT logo on them. In fact, BT boxes at all? It didn't exist then.
Continuity mistake: The guy that broke his own neck in the interrogation room strangely appears in the next scene, where Angle loses her head. His face is shown in close up twice. (00:15:13)
Factual error: When Mike is in Idaho he has a clear view of Mt. Hood. Even if it were possible to see the mountain from so far away (over 200 miles), there is another mountain range lying between Idaho and Mt. Hood, blocking the view.
Continuity mistake: The position and intactness of the biscuits changes between shots, as Louison puts the sugar pot on the biscuit plate because the tea begins to overspill from the cup. (00:27:20)
Continuity mistake: At the end when Jack (Ethan Hawke) is nailing the roof of his cabin he stops and looks around with the nails in his mouth. His head turns and the camera goes back and forth and suddenly the nails are in his hand. He then runs down the latter with no sign of the nails anywhere.
Continuity mistake: As the cops are taking the Hit and Run Son away, notice he his carrying a red plaid tote bag. Later in the movie, it miraculously appears in the possession of Still Working on the Same Painting. It can be plainly seen as she and her friend, Having a Day, are walking into the city sunset.
Continuity mistake: When Sonora does her very first dive, we see Clifford release Lightning and he begins to trot up the ramp. In the next shot, the camera shows the front view of the horse, and he is cantering up the ramp. Then the camera goes back to Lightning's front view, and he is trotting again.
Continuity mistake: When Richie shoots Bobby on the sidewalk, after he spits on him, he walks to the road to get into the red sports car. Bobby's wife then runs over and gets on her knees to attend to Bobby, there is no red sports car on the road in the background, but in the next shot it shows Richie getting into the car and taking off from the position the car was originally waiting.
Revealing mistake: During the night surfing scene notice that the sun is evident in the background (look closely it does not appear long). There are also shots where you can see clouds and faint blue sky. Moments later you see Keanu and Lori sitting in the water with completely different lighting which was actually taken at night and further distinguishes that the surfing shots were not actually done at night time. I heard the scene was shot during the day with a filter so it looked like it was shot at night.
Continuity mistake: When Ruth climbs onto the train her shoes have rather high heels. When she jumps off her shoes are flat, but when she gets up the heels are back.
Revealing mistake: When Dani goes to meet Cort after dark to go swimming, you can plainly see it's daylight out because the sun is shining.
Factual error: In the scene where Earl is fighting the other prisoner, he is using a "sword" made from a bar of metal, it has a blade that is well over 2 feet long from the tip to the hilt. At the end of the fight the other prisoner is standing with his back against a solid concrete pillar, but Blake somehow manages to shove the "sword" through him all the way up to the hilt. This wouldn't be possible unless Blake were somehow able to shove the bar into the concrete.
Continuity mistake: When Larry is burning his books he throws one at Dorothy who is looking out of the window. The upper right part of a window pane breaks, but in the next shot the left side is broken. (00:11:20)

Continuity mistake: When Frank Jr. is laying in the hospital bed and the doctor comes over; the doctor has his hand up near his face when the camera is behind him, but when it's in front of him, his hand is down and off screen.
Continuity mistake: Towards the end of the movie two of the mob goons are dangling Patrick Dempsey over the rooftop. After a brief scuffle Dempsey is hanging on by one of the men's pants, which are ripped down to his ankles. When it shows the pantless goon fall off it cuts to inside where the mob boss sees him through the window, but his pants are now pulled up.
Revealing mistake: When Willard goes prawn fishing with Ben he helps him sorting out the prawns from the catch. However, even though he does this right after the net has been emptied out onto the deck all fish and prawns are already dead.
Continuity mistake: When Fred is talking to Jane about macrobiotics, he had a band-aid on this head. How did that happen? He got a band-aid why he got whacked with the globe, which comes later in the movie.
Revealing mistake: During the beginning, as the newspaper headlines roll, the small text in the articles is actually the same text repeating itself over and over again, something like: "an investigation issued."
