Other mistake: In the music within the ending credits, the lyrics incorrectly state that Raph is the leader of the group when all Turtle fans past and present know it is Leo.
Visible crew/equipment: When Sarah is fighting with Garcia in her home, for a brief moment 2 crew members are seen, one in white shirt and beige pants (looks like director Clint Eastwood) and the other wearing a blue shirt and dark pants. (01:24:15)
Continuity mistake: When Ford and Jazz are at the Colleen Sutton party, Jazz is asked to keep an eye on Colleen. Collen spots her and put a CD down her dress with the black end facing downwards. When Ford is taking the CD up from her dress the black end is now facing upwards. (00:43:25 - 00:45:00)
Revealing mistake: In the opening scene where the zombie kills Johnny. When they fall against the tombstone you can tell it is a dummy.
Revealing mistake: During the big fight scene, just as Annie Wilkes falls to the floor and hits her head on the typewriter, the actress is replaced by a really bad looking Kathy Bates dummy!
Revealing mistake: When the lawn mower the heroes send off as a diversion crashes you can see a wire pulling it. (01:01:30)
Continuity mistake: In the scene when Billy is shooting Doc's handcuffs, Billy's revolver changes several times, shot by shot. Watch for the front sight to appear and disappear between the POV Doc shot and the medium distance shot, and for the entire finish of the gun to change at least twice.
Revealing mistake: When the ferret bites Crisp, it is a stuffed (dead) ferret. The mouth does not close.
Visible crew/equipment: When Jake is on the medevac helicopter headed to Billie and Little, you can see the film crew in the bottom left of the screen, before it lands (this is not visible in the widescreen version). (01:18:00)
Continuity mistake: When a man is giving a locket with two pictures, he places it on his left hand, yet the close-up shows the right hand.
Revealing mistake: When Tom Cruise and his girlfriend are visiting his former arch rival and now good friend, his wife calls Tom "Tom", not by his character's name.
Continuity mistake: When Molly takes Mikey into work and he is under the desk, Rona is still wearing her shoe. Yet when the scene changes, her shoe is missing when Mikey starts tickling her foot. Then when the boss realises that Mikey is under the desk, her shoe is back on. When the shot changes again, her shoe is off.
Factual error: Cher complains that Astroturf is going to ruin baseball. Mermaids is set in 1963 when Astroturf was still being developed under the name Chemigrass. It wasn't christened Astroturf until it made its world debut on the floor of the Houston Astrodome in 1966.
Revealing mistake: When Melanie Griffith comes home from the jail, as she opens the door you can see there's no wall, it's just the door.
Continuity mistake: When Andy is tied up on his bed, the two skipping ropes tied to his feet have green rope, but in one closeup of Andy kicking his foot about, the rope is yellow, then in the next wide shot, is green once again. (In the closeup of Andy kicking his feet he has also gained slippers!) (00:28:35 - 00:29:40)
Visible crew/equipment: When the baby in the baby stroller is rolling down the cliff hills, a safety wire attached to it is briefly visible, as Luke chases after it.
Continuity mistake: In one of the final scenes where Tom Selleck has a gunfight with Alan Rickman, the time of day during the few minutes (in movie time) the scene takes place varies from noon (full sunlight) to dusk. Just prior to the gunfight, when Selleck is getting ready to draw on Rickman and his two henchmen, there are almost no shadows and there is bright sunlight indicating it is in the middle of the day. Just after the gunfight there are now long shadows on the characters and moments later the camera pans across the hills and the sun is setting.
Suggested correction: Shadows exist before and after try to watch it again.
Continuity mistake: When the Drapes are singing to Allison/Baldwin/Mrs. Vernon Williams, the song, "Gee, I Love that Girl" in the speeding cars, Hatchet-Face's gold earrings are on, then off, then on again. They are seen again in other scenes.
Revealing mistake: In the extended version of the film during the buffalo hunt, there is a shot of a buffalo making a turn and in the distant horizon, you can briefly see a modern radio tower on top of a hill.
Revealing mistake: In "Cat from Hell" the cat crawls back out of Halston's mouth after the clock strikes twelve at Drogan's return. As it exits, the mouth and face collapses and is quite obviously made of rubber. (00:54:45)
