Continuity mistake: When Charlie Epps is writing a quadrillion on the whiteboard, the writing alternates between shots. Most noticably when he first writes it down, there is a significant downward tendency of the 000 groups. In the next shot, they are pretty much horizontal. Also the shapes of the commas alter.
Factual error: In the whole episode, Romania is depicted as a monarchy with the king in a position that allows him to make political decisions. However, Romania ceased to be a monarchy in 1947. By the time depicted in the episode (circa 1997), Romania was a republic and its head of state was the president. Members of the ex-royal family did not hold any positions in the Romanian government and were certainly not authorized to represent Romania in international events.
Visible crew/equipment: At about 30 minutes into the episode, right after Cal says: "if Jeffrey knows about priox, he's going to jail. But I'm gonna be damn sure before I send him there", you can see a hand in the top right corner of the screen.
Continuity mistake: The blood Ashe smears on her face changes its pattern and consistency several times as the shots change. (00:36:00)
Lady Killer - S3-E3
Continuity mistake: Root shoots the hitman, walks up to him and slides his gun a couple of feet away. A wide shot shows the gun where it should be. After she says "you're the boss" and starts walking away, we see exactly the same angle, the gun has vanished, and some random black bits have appeared.
Clash of the Megazords - S1-E29
Other mistake: When TJ goes to get the Phantom Ranger's ruby, he is standing on top of the battery pack on the Turbo Megazord. There are no other places for him to stand. After he destroys and knocks off the battery pack, in the next shot he is still standing in the same place, but there is nothing for him to stand on.
Sasuke and Sakura: Friends or Foes? - S1-E3
Continuity mistake: During the scene where Naruto and Sasuke accidentally kiss, Naruto's whiskers are gone.
Factual error: In the episode where Sydney is supposed to be in Helsinki, there are visible skyscrapers in the background. There are no skyscrapers in Helsinki.
Episode Nine - S2-E2
Continuity mistake: The necklace James took from the coconut in Dr. Jacobi's office in the previous episode had a gold chain. When he gives it to Agent Cooper in this episode, it's on leather.
Continuity mistake: All shots of the Jeep Cherokee prior to it crashing (and during the process of flipping over) show that it wears factory-optional silver steel wheels of a 'star' style. But as the wreck settles upside-down, it's wearing plain steel wheels (like those found under full wheel covers or on a spare tire).
Plot hole: Throughout the series, auxiliary characters are always far too willing to give all kinds of information to Tru. Doctors and registrars constantly give her privileged information about patients and students. Tru is often able to retrieve information like addresses and phone numbers from people's service and utility companies, when normally you must verify your own information before they will even talk to you about your account. Of course there can't be an episode if Tru doesn't quickly find the person who asked for her help, even though she doesn't usually know much more than their name, but it's still a bit conspicuous.
Factual error: When Tom has decided his scout group will have to go for the food and then his look for his son later, they are stood on a green. There is a war memorial dedicated to both World Wars, 1914 - 1918 and 1939 - 1945. That's got to be in Canada, as the USA didn't enter either war until later than those dates. (00:28:00)
Factual error: When printing the image of the painting, Stella uses the printer driver "Microsoft XPS Document Writer" - which would save the output to a file. However, she still gets a printout from the printer in the office. (00:02:30)
Suggested correction: Microsoft XPS Document Writer creates a document in XPS format then prints said document. I use it at work. It works in the same way as "print to PDF".
Tiger Left, Tiger Right - S2-E6
Continuity mistake: Kimble's been kidnapped and held for ransom. He had nothing with him when he was taken, yet when he leaves the abandoned house with the kidnappers, he has a small suitcase. When they drop him off on the road, he doesn't have it. When, in the epilogue, he's shown walking, he's carrying a different, larger suitcase. (00:46:00 - 00:49:00)
Plot hole: The FBI is looking for a "very tall" guy who has been identified as such by various witnesses and by their own expert due to the entry angle of a fatal bullet wound - 6'5" at least. They send Elena into a bar near the end of the show to meet the Albanian perp who when he arrives is barely average height.
Continuity mistake: Tenaya 7 is running on the treadmill in flat sandals with tan straps, she then has flat sandals with black straps as she fights the guards.
Plot hole: Parker gains access to the external room using a valid security card, they figure out the CEO's passcode which opens the burn room door...and yet the room inside is still protected by a swarm of lasers. Was the CEO supposed to dance through the laser sensors like Parker does every time he goes in?
Revealing mistake: When Briggs disguises himself as Rogosh's defense attorney, the glasses he puts on very obviously have no lenses in them. (00:26:05)
Revealing mistake: When Danny is driving Mr. Zhao in his convertible at night, you can really see that the background is a bad fake and since even though Danny is driving with the top down, his hair and clothing does not get ruffled at all by the wind.
