American Psycho pictureAmerican Psycho mistake picture

Visible crew/equipment: In the scene after Patrick Bateman's second encounter with the detective in his office, we see Bateman having sex at Courtney's apartment. After he rolls off her, Bateman approaches the large, stand-up mirror in the bedroom. In the upper right hand corner of the mirror, a boom microphone can clearly be seen moving around to pick up Christian Bale's lines. The next time we get the same long shot, the microphone is gone.

The Omen picture

Visible crew/equipment: When the ambassador and the photographer are in the cemetery getting attacked by the dogs there are men standing behind a tree. I'm assuming they're the trainers - they are located when the photographer is trying to hop the fence. Look in the back right hand corner - there are about two or three men standing there. (01:21:15)

Resident Evil pictureResident Evil mistake picture

Continuity mistake: Near the beginning of the movie, Milla Jovovich reads a note that has been left on the desk. She didn't write it, as they demonstrate in the film. However, when they do show the person who wrote the note composing it, the handwriting is different from that in the note from the earlier scene. (00:10:20 - 01:12:25)

The Thing picture

Plot hole: Through this film (and its predecessor) it is established that the creature imitates its victims perfectly, having all of their knowledge and memory. At the end, when the female lead tells the male lead she knew he was human because of his earring, he reaches for the wrong ear, confirming he is The Thing. Even if The Thing couldn't reproduce the earring, it would have known which ear it was supposed to be in.

Suggested correction: It is also established in this film that the creature cannot perfectly imitate inorganic materials; the tooth fillings, metal plate, etc. Kate knows that Carter is The Thing and asks him a trick question about his earring to confirm it. The fact that The Thing reaches for the wrong ear means that it didn't know where the earring really was because it cannot perfectly imitate inorganic materials. There is no mistake here.

Continuity mistake: When Danny goes to their old room at the Overlook, the bathroom door only has one broken panel but in the Shining, both panels were smashed when Jack heard the Snow Cat arriving.

Prometheus picture

Factual error: The type of surgery shown made by the machine transversely cuts the rectus abdominis muscles. Besides not being a standard surgical incision in order to "remove a foreign body" as stated, it seriously damages important muscles of the abdominal wall making any immediate active mobilization of the trunk virtually impossible, even under strong analgesia.

Friday the 13th Part V: A New Beginning picture

Plot hole: When the cop shows Pam the newspaper clippings they include what look to be fresh photos of the real Jason from the events of Part IV, yet no photographer is ever seen taking pictures of Jason alive in the previous films and most likely wouldn't live long enough to publish the photo. (01:25:00)

Wrong Turn 2: Dead End picture

Continuity mistake: Towards the end when Nina is tied up around the wrist with razor wire and Dale shows up to rescue her by putting his knife in the wire to free her, suddenly the wire has changed and is extremely loose. Before it was bigger and tightly tied around her wrists.

Friday the 13th picture

World War Z picture

Factual error: An An-12, the aircraft the main character uses to fly all over the world, has a maximum range of about 3,500 miles. Hardly enough to fly from the US to South Korea or from South Korea to Israel. The An-12 also miraculously transforms into a C-130 in a couple of filler scenes. And why is this ex-Soviet aircraft marked in USAF markings, assigned to McGuire AFB?

Suggested correction: Can't speak to the second half of your paragraph (should really post as 3 separate mistakes) but as for the first, a range of 3500 miles, aircraft such as the kc-135 exist and aerial refueling is fairly common place. Considering it's a mission supported by the acting UN Secretary General to stop a world crisis, resources could have been diverted for refueling.

Bride of Chucky picture

Plot hole: In the end of the film it is heard the police want to exhume the body of Charles Lee Ray from his grave site in New Jersey. Now when Chucky and the crew get to the grave site they find and kill a coroner who is digging up the body. He is the only one there at 1am, by himself, a lonely coroner without any police officers, after all this is a police investigation and I doubt the cops would have him there alone. Then right at the end the Detective who is hunting them arrives. Now he is a cop from Lockport, about six states away. A. Why did he drive all that way to see the body? B. A cop from all the way down there shows up but no new Jersey cops are at the scene?
