Other mistake: When Regine becomes the new host of Fright Night, she appears on video monitors and Peter Vincent is watching her on TV while in a bar. Cameras use mirrors, so she shouldn't have appeared on the monitors or on the television at all.
Suggested correction: Most cameras don't use mirrors. Only DSLR/SLR cameras do, which allows you to use a viewfinder. Other cameras, camcorders, and television cameras don't need mirrors.

Other mistake: Watch when Carol is singing "Oh Come All Ye Faithful," as she walks down the line of on-lookers, an extra in the back moves along with her and keeps looking at the camera.

Continuity mistake: When Poirot moves across the beach volley (ship volley?) court, a girl in an ample blue skirt is moving left to right towards him, and is completely gone at the cut. (00:16:45)

Other mistake: Christina suggests that they have found Atlantis. However, they start in Hawaii, which is in the Pacific. The general consensus is the Atlantis is in the Atlantic (or Mediterranean) and not the Pacific. Some people do suggest that the lost continent of Mu is in the Pacific.

Other mistake: Amazing that nobody sees the hooker's dangling body before that boat tour which looks like it's around nine, plenty of time for somebody else to notice her.

Visible crew/equipment: When Guarino is being taken away by The Hunter, you can see the rope used to pull him in the upper right corner of the screen. (00:46:05)

Factual error: The timeline is flawed. Baseball season typically runs Mar/Apr through Sept/Oct - Michael was on teams in FL then NJ. The Spartanburg newspaper article Harry was reading the morning after the Popes fled FL was dated Mar 19, 1987 - Spring. Travelling to NJ as well as during the Popes' stay there, all tree leaves were green - Summer foliage. After asking Michael where he was applying to college, Lorna told him he'd have to apply next term - meaning January. So, was it Spring, Summer, or Fall?

Plot hole: At Tim's funeral, Olivia's attorney tells her that Tim had himself removed from Olivia's Last Will and Testament, proving he loved her and didn't want her money. However, an attorney could not legally change a client's Will without that person's knowledge and drafting a revised version.
Suggested correction: Not true. Anyone can have themselves removed as a beneficiary of a will. This is done by signing an Affidavit of Disclaimer of Inheritance at such time as someone becomes aware that they have been included in a will as a beneficiary. This is what Tim meant when he said he had removed himself from Olivia's will.

Continuity mistake: The main villain is trying the soft approach and wants to persuade David's ex-wife to side with him. As they are having a conversation about the bank loan, John Steiner's glass is raised - or not - depending on the camera angle. (00:37:00)

Visible crew/equipment: When Nicolas Cage returns to his apartment, you can see a crew member reflected in the mirror on the wall right after Cage passes in front of it. (00:11:35)

Factual error: The Los Angeles cops pursuing Lulu, Peaches, and Darlene in Mexico couldn't arrest them due to this being a foreign country where they wouldn't have jurisdiction.

Audio problem: When in the bar before being put in the cell, Dolph grabs a gun from an MP and starts shooting up the bar. The sound of gunfire starts a split-second before he starts shooting.

Revealing mistake: When one character's killed, stomach sliced open, you can see the wire yanking open the prop stomach to the left of the camera.

Revealing mistake: When Jemma enters the headshrinker's laboratory, there is a table with three heads on it each encased in glass. When it goes in close-up on the middle head, you can see that the table has a hole where the actor can slip in his head.

Revealing mistake: Clearly not Susan Blakely when she goes topless. Her hair suddenly becomes curlier, that's a body double.

Continuity mistake: When the condo manager shows up at Billy's house to take Purple, and chases him round the garage, some stuff, including a white plastic basket, falls off a shelf twice; first in the wide shot, then again in a closeup of Purple's feet.

Revealing mistake: In the scene where Zuckerman is thrown to the floor in the gym and handcuffed, you can hear the handcuff ratchet click as it's placed and closed on her wrist. As the other agent moves away, you can see that the handcuff is open and not actually closed around her wrist. (00:31:00 - 00:31:50)

Visible crew/equipment: A boom mic is visible when Charlie and Scully are talking while walking. (00:16:00)
