Scream 2 (1997)

Visible crew/equipment: If you look really close in the background as the killer throws Cici off the balcony, you can see someone sitting in a tree, wearing black, with a camera.

00:33:35

Audio problem: When Dewey is being stabbed up against the soundproof glass, you see a shot of Gale shouting "No." You can see a reflection of the killer in the glass standing motionless, but you can hear Dewey being stabbed.

01:18:45

Revealing mistake: When the killer is attacking Cici on the balcony, you can see blood on Cici's back before she is even stabbed and both times she is stabbed, the knife that comes out of her back has no blood on it.

Continuity mistake: Hallie takes the remote control off the top of the TV to turn it on. But later when they return in front of the TV to watch the news report, the remote is back on the top of the set. Also, the position of the video console which is also on top of the TV has changed, the position of the clothing on the chair next to the television has repositioned and lastly, the items on the window sill behind the TV set have completely changed.

00:10:20

Revealing mistake: When Randy, Gale, Dewey and Joel are sitting on a bench in the school grounds, Gale is smoking; but no smoke comes out of her mouth when she takes a drag, nor does the cigarette have any smoke coming off it.

00:58:35

Revealing mistake: Just before the cop gets impaled through the head by the pole, you can see that it is obviously a dummy.

01:23:45

Other mistake: When the killer is stabbing Randy, you can see his reflection in the side mirrors. He stabs him many times. The same amount of blood is on the knife every time he lifts it up.

01:02:45

Visible crew/equipment: In the scene where Cici is killed, just before the killer throws her off the balcony there is a visible member of crew/stunt's head.

00:33:50

Continuity mistake: When the Sheriff writes "Cici Cooper" on the chalkboard, between the closeup and wideshot of him writing, the handwriting and location of his writing dramatically changes, and the words "Maureen Evans" and "Phil Stevens" above, also change too.

Revealing mistake: In the opening scene when Phil gets stabbed in the head, watch carefully and you can see the retractable blade popping back out when he pulls his head away.

00:08:05

Revealing mistake: When Cici is stabbed in the sorority house, her shirt is bloody, but there is not a hole in the material.

00:33:20

Character mistake: During the scene in which they are all arguing whether or not film sequels are better than the original or not, someone says Sigourney Weaver's classic line from the movie Aliens: "Get away from her you bitch", and Randy makes a smart comeback and tries to correct him by saying "I think the correct line was 'stay away from her you bitch'. This is a film class, right?" Wrong - the first guy was right. This line is truly unconvincing for the Randy character, being a big movie buff and all. Jamie Kennedy decided to improvise as Joshua Jackson actually made the initial mistake by saying the wrong line, causing a different mistake.

Add time

Revealing mistake: When Mickey is flying through the air after getting shot at the end of the movie, if you look closely you can see it's a stunt double.

01:46:00

Continuity mistake: When Gale kisses Dewey she has no more lipstick on her mouth, then in the next shot she has lipstick on.

Add time

Revealing mistake: When Mickey draws the gun at the end of the movie, a hammer is heard being pulled back. Yet the gun that Mickey is using is hammerless.

Add time

Continuity mistake: The killer throws Cici off the balcony facing the ground. In the next shot of her falling, she's flipped over on her back.

Add time

Continuity mistake: When Cici is thrown from the balcony there is debris from the window all around her (glass & window pane fragments), but if you watch when she is thrown through the window in the first place, it is only a bit of debris went that far away, not nearly as much as it is shown around her.
