Visible crew/equipment: When Julia's attacker ties her up with the lamp cord, in two of the shots facing Julia the boom mic can be seen above her at the top of the screen.
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.
Revealing mistake: Clearly not Susan Blakely when she goes topless. Her hair suddenly becomes curlier, that's a body double.
Visible crew/equipment: At the end, the helicopter filming the shots of Dallas is blatantly visible in one of the buildings.
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)
Character mistake: Kathy Ireland as Wanda speaks mostly in a slightly squeaky voice. But in one scene she uses her own regular voice.
Continuity mistake: Many editing mistakes with the 'accidents' including the guy at the weight set, when his ribs crack through his skin. In the following shot all is normal again.
Continuity mistake: When Chris has a gun aimed at Evelyn he's holding it with his right hand. A shot behind him and suddenly it's in his left hand.
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.
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 events in the film take place in mid-1929, as evidenced by the first Academy Awards being presented in May. However, Wyatt Earp went to the happy hunting grounds in January of that year.
Audio problem: When Carrie Fisher and David Soul make out in Trieste, a performer at the local restaurant is supposed to be singing the popular Italian song "Torna a Surriento", but his lips barely even move and it's self-evident that he's not the one singing. (00:11:30)
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.
Other mistake: Amazing how quickly the killer, armed only with a butcher's knife, could behead a guy under water before killing the other one.
Continuity mistake: Clearly a different guy playing Zack in the beginning as he looks to be over six feet tall and has a full head of combed back brown hair. Zack later on looks like he's only 5'5" with receding brown hair.
Continuity mistake: In the restaurant scene where Annie meets her father, what is to her father's left varies with the camera's focus. Views facing Annie show a piece of panelling or plywood to her father's left but views facing her father show a large vase of flowers. (01:34:45)
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.
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)
