Other mistake: The Sliders discover the reverse-time issue when they notice that the clock on the wall is backward. However, in other shots, clocks look normal. Look carefully at the clocks on the judge's desk as the camera pans by.
Other mistake: The Monster appearing in the pilot and causing the turbine to explode is a mistake (not trivia). This is actually an artefact of poor CGI effects that was left in the show in error. It was confirmed by the producers. You can see it best here: http://www.lostpedia.com/wiki/Image:Turbine_Explosion.gif.
Other mistake: The battle droids - including the commando droids featured here - habitually have two broad fingers and a thumb. So how can a commando droid squeeze itself completely into clone trooper armor without its broad fingers tearing open the gloves, since it can't separate its fingers?
Other mistake: Throughout the episode, including the very first shot, we see the sun is shining brighter and hotter than usual. This lends credibility to the theory that Superman's powers are responsible for increased solar activity. Later on in the episode it is revealed that the heatwave is being orchestrated by Lex Luthor, who is is heating an underground river to coincide with Superman using his powers. Lex does not however have any control of the weather, and no explanation is offered for why the weather conveniently 'played along' with his plan.
Other mistake: When O'Neill first goes to visit Teal'c in his cell the symbol of Apophis on Teal'c's head is upside down.
Other mistake: The crest of the clone trooper's helmet, when he points out that the cannons are being destroyed, does not reach down to the eyeslit, whereas it does with the others'.
The Dog Who Knew Superman - S2-E9
Other mistake: A gangster pushes a dog into a well and the dog can be heard splashing around. The man's wife is furious and several people are unable to retrieve the dog. Superman tunnels into the ground and into the bottom of the well and emerges holding the dog. Both he and the dog are completely dry.
Other mistake: In the hotel room shootout, bullets are being fired through the wall easily and tearing up the place as you'd expect. Frank then dives through the damaged wall and they shoot at each other with Frank behind a cupboard and Pilgrim behind an internal wall. But bullets empties into both of these bits of flimsy cover leave the men behind them miraculously unscathed.
The Contest - S1-E24
Other mistake: When Tom unzips the backpack to collect everyone's devices, he adds a few devices that belong to Ben, and as Tom drops in sneaky Ben's last device, watch as the backpack zips itself shut mid-shot, all on its own. (00:04:32)
Other mistake: After King Tut's men deliver the statue, it's referred to as a Sphinx. Even Batman says, "Rather good imitation of the 4th Dynasty's Sphinx at Giza." Problem is, the Great Sphinx of Giza is a reclining lion with a human head. The statue in Gotham's park is a ram's head atop a seated human body, resembling Egyptian God Khnum, and looks nothing like the Egyptian Sphinx. Bruce Wayne is a member of Gotham City Museum's Board of Trustees, which recently opened the new exhibit of Egyptian antiquities. (00:10:35)
Other mistake: For secret agents, Sydney and Dixon are not very dedicated to secret identities. At several points they refer to each other by their real names in front of other people while they are under aliases. Examples include The Confession party and The Coup Las Vegas scenes.
Other mistake: Two Borg are discovered North of the Arctic Circle. One is covered in ice, the other encased in ice. Carbon dating shows the wreckage to be over 100 years old (to tie it in with Star Trek: First Contact). The Borg are inactive and unable to repair themselves until they are "defrosted". The temperature above the Arctic Circle doesn't usually drop below -100°F. The Borg have been shown to work very well in the vacuum of space which is 3-4K (roughly -454°F). If they can survive that, even being frozen in a solid block of ice would not slow them down. The nanites have to be in their "blood" and operate at the cellular level. That cannot be damaged by re-entry and the crash.
Saga of a Star World (1) - S1-E1
Other mistake: In the second shot showing the fleet of Battlestars (from the port side and slightly behind), the closest ship has an odd reflection which forms a "pillar of light" radiating down from near the rear of the landing bay. It is an effects error, perhaps created while trying to hide the rod that holds the ship up from below. (00:02:45)
Other mistake: In the party/orgy scene where Aetius is showing off Rome to Attila, one can see a woman with her back to us reveal herself to a man and woman. Despite her veil, one can see her thong underwear. This type of underwear is a 20th century innovation.
Other mistake: When Spike is thrown out of the base by Megatron at the end of the episode, Optimus calls him 'Splik'.
Other mistake: Ethan is seen playing a Game On a computer, Connor comes in and Ethan looks away from the computer to talk to him. The game Ethan was playing is still going, but Ethan has stopped playing, obviously a demo.
Other mistake: When Don and Dr Smith are stealing Sesmar's control unit, look closely at the base of the electronic arch - Raddion is hidden from sight but the careful eye will see his golden feet.
Other mistake: When assembling the Zeo Megazord, Zeo Zord V is the last to join, forming the head and back of the Zeo Megazord. When it has connected, we see all 5 Rangers slide down simultaneously into the head of the Zeo Megazord. Where it is piloted from and where did they slide down? The head has only just joined, and the other 4 Zeo Zord forms the rest of the body - not enough time for them ALL to slide up, and then back down again.
Other mistake: In the scene where Drakken accidentally "clones" Bonnie Rockwaller instead of Kim Possible, he holds up a picture of Kim to compare the results of his experiment with the real thing. The Bonnie clone, completely encapsulated behind the glass of Drakken's cloning machine (as evidenced by the reflection of light off of it) somehow manages to get a hold of the picture despite this barrier. (She does this without having to break the glass.).
Other mistake: In the CIC, Tigh challenges Apollo and asks why he isn't in the brig. Shortly after Apollo begins to explain the plan for the search and rescue of the Raptor downed on Kobol. He refers to it as "Raptor 3" when it is Raptor 1 they are looking for. Raptor 3 was destroyed when they first jumped to Kobol, Raptor 2 escaped back to Galactica, and 1 fell to Kobol. The Raptor on Kobol is referred to as Raptor 1 throughout the rest of the episode and on preceding episodes.
