Revealing mistake: When the ambulance is hanging over the cliff, in the wide shot you can see the cable holding the ambulance safe. (00:50:40)
Revealing mistake: The double-bladed axe one of the Decimas uses to attack the station windows is wobbling as he strikes with it. Small wonder he's not getting far at breaking in, with a weapon made of rubber. (00:22:30)
Revealing mistake: When Alan serenades Jill, near the end of the song, the guitar player removes his hand from his guitar briefly but the guitar part continues to play (it's being synthesised as part of the keyboard's rhythm track). (00:19:10)
Revealing mistake: When Fran is on the private jet, the champagne sitting between her and Cathy doesn't move through all the turbulence, showing that it is the camera shaking and not the plane.
A Weekend in the Country - S3-E3
Revealing mistake: When Orson and Andrew are sitting in the diner, the same man in the green shirt keeps passing the window.
Revealing mistake: The money that Micah dumps out of his backpack is very obviously fake. In fact, the $20 bills have Benjamin Franklin's portrait on them.
Revealing mistake: In the scene where the king and his entourage are walking through the crowd, someone in the crowd (right side) is wearing a watch on his left hand while applauding.
Saga of a Star World (1) - S1-E1
Revealing mistake: In the second shot showing the fleet of Battlestars (from the port side and slightly behind), two ghostly images fly in formation with the three Battlestars shown. They are just above the closest ship (where the narrow middle meets the larger rear section). It seems that the shot may have originally contained 5 ships and an attempt was made to 'remove' the most distant two, leaving the "ghosts". (00:02:45)
Remy Rides Again/Hassle in the Castle - S5-E10
Revealing mistake: In the episode Hassle In The Castle, in the hall of Infamy the name plates are either scribbles or they're just blank.
Revealing mistake: When they are escaping in the beginning of the episode, watch Rodney dial. As he finishes, one of the DHD address panels pops out and falls off.
Lows in the Mid-Eighties (1) - S3-E8
Revealing mistake: At the party it is obvious none of the red plastic cups have drink in them. (00:45:00)
Revealing mistake: "Alan a Dale": Lady Mildred rides side-saddle. But when Gisburne gallops away with her, some shots reveal that the stunt woman riding the fast-moving horse is astride it full straddle. Her skirt is blown back just enough to see a brief glimpse of the stunt rider's real leg on the horse's right, and the fake pair of legs in side-saddle position on its left. For just a moment, the lady appears to have three legs. (00:20:00)
Revealing mistake: When Frasier comes into the chalet after skiing he doesn't show any of the visible effects after a hard day on the slopes. Meaning, his face isn't even flushed from the cold, his hair is perfectly combed after wearing a hat and there is not even a drop of snow on his boots.
Revealing mistake: When the first scene at Emma's hideaway was shown, obviously the two characters Emma and Jessica were filmed seperately on the couch and then the film was put together (as both are played by Angela Lansbury). However Jessica did a lot of moving while she was talking, so Emma was looking straight across at where she had been, despite her bending down while she talked.
Revealing mistake: In the parking lot shot, one patron of the Leisure Center warns an arriving patron that Brittas is back, prompting the arriving person to reverse their car out of the parking space. However, note the arriving patron's hands - his car was already in reverse before he was spoken to. (00:12:15)
Six Strangers at Apache Springs - S2-E7
Revealing mistake: During the saloon brawl, recycled footage causes Curry to change into his first season hat for a few shots. After the fight, he has his second season hat back on. (00:28:00)
Revealing mistake: When Leland Palmer is locked in the cell he starts screaming and runs headlong into one wall, then the other. The first wall wobbles noticeably on impact, indicating it is being shot on a set.
Revealing mistake: When Patsy knocks down the black guy with the iron pole, the pole breaks in half like a piece of plastic. When it cuts, the pole is intact.
Revealing mistake: When Topanga is "naked" under the cover, at one point, you can see a large corner of her bra. (00:02:58)
Revealing mistake: If you look carefully when Neelix shoots the bins of water causing the water to rush out you can see a faucet opening on one of the bins.
