Continuity mistake: The beginning scene involves two kids in the finals of the school championships. Why are there only adults watching? In a children's tournament all the other kids would most definitely be watching this game.
Continuity mistake: When crackhead drug dealer stabs Mr. Big at the table in the club, the boss pulls a table cloth, upsetting crockery. In next shot it's all perfectly tidy.
Continuity mistake: In the outdoor restaurant scene (where Tim Robbins has just spoken to Burt Reynolds), the waiter brings Tim Robbins a bottle of water and a wine goblet, but when he pours the entire bottle of water into the goblet, it's obvious that it was not a full bottle of water to begin with. It doesn't fill the glass of half way. A waiter would not serve an opened bottle of water to a diner.
Continuity mistake: When Levoi and Crowhorse visit Grandpa for the first time note the white and black beaded belt on the table behind Grandpa. In the beginning it hangs at the edge just at the first black stripe. Just after Grandpa trades Levoi for his glasses and hands him the rock, the belt now hangs nearly to the second black stripe. After that cut the belt now hangs in its original position. (00:37:30 - 00:38:30)
Visible crew/equipment: In a later scene, when Kim Basinger comes to see Richard while he's in custody, you can very clearly see the boom mic over their heads.
Visible crew/equipment: After Ivy and Sylvia crash into the tree you can see the reflections of the crew and the boom mike on the side of the car when Ivy wakes up.
Other mistake: The steamship shown in Patriot games is actually a shot from John Wayne's 1955 Sea Chase.
Suggested correction: The use of stock footage in movies is a common practice. More context would be needed to explain why this is a mistake.
Visible crew/equipment: At the end when Dr. Angelo and Peter are escaping the blast, just after Angelo jumps down over the facility wall and calls for Peter to follow, for a second you can see someone holding the back of Peter's shirt to help him drop down, or it might be a rigging of some kind.
Revealing mistake: When Lance Henrickson's character gets killed, there's a close-up of his flashlight lying in the snow with a rivulet of blood flowing past it. It's very obviously fake snow, since there are snowflakes floating on top of the blood.
Continuity mistake: After Claire punches Peyton for the first time, there is blood on Peyton's face. When she gets up off the floor, the blood is completely gone.
Revealing mistake: When Nick returns to his apartment (after being made invisible) he immediately closes the curtains. Although he is invisible, we should see the curtains pulled closed at the point that he grabs them with his hands. Instead we see them close from the top, revealing they were closed either by a crewman or an automated process. Note: The curtains are NOT meant to be automatic in the film as we see and hear him physically close them.
Continuity mistake: When Ray Liotta throws Madeline Stowe on the bed after she pulls the gun on him, he used his hands to pin her arms down. Then they cut to a different angle, her arm is pinned under Ray's leg and he's grabbing her hair.
Other mistake: When the girl throws a grenade at the closed window it rolls a bit and you see that the bottom has been drilled out.
Continuity mistake: When Chet and Stanley asks Irene some questions (in the café, about 15 minutes into the movie) about the murder, the cigarette Irene smokes changes a few times between the shots. Most obvious is the length of the ashes. (00:16:13)
Visible crew/equipment: After Jack jumps out of the plane he comes close to another Flying Elvis, who is being suspended from a visible cable.
Continuity mistake: In the last scene, Tanya gets her arm cut on a piece of glass in the window by Charles, just before he turns to fight a cop. In the next shot the glass has disappeared from the window completely.
Plot hole: There's no way Dr. Lynn Waldheim's coat would have fitted Carter.
Continuity mistake: Brian Hornsby is being questioned by local investigator Alfonso Rodriguez. While he listens to him, he flips through a few photos of Rodriguez' s romantic endeavours. He picks from the pile the last photo, but in the next shot the photo he shows him was the topmost one. (00:12:40)
Other mistake: Early in the movie the robbers need to enter a code - the code they get by force is "7465" but the code that the leader of the gang enters is "7466". (00:12:50)
