Christmas Special: Part 2 - S3-E2
Plot hole: Lee and Dawn overstay their tourist visa in the US, then fly back to the UK for the Office Christmas party. They then get into a taxi to go out to the airport in order to return to the US. They're kidding themselves. As I know (to my cost) when you overstay a tourist visa, the US Immigration Service finds out when you check in at the airport on departure. They'll be refused reentry, and probably barred from entering the US for up to six years. (I got a three year ban.) Neither Lee nor Dawn could possibly be unaware of this nor think they could beat the system as they would have been arrested when they checked in in Florida on departure (as I was), and they would have remained in small holding cells until the paperwork banning their return had been processed and their passports stamped 'Invalid for U.S. Entry', as mine was. (All this takes about seventy two hours, so they'd have missed the Christmas party anyway.) The mistake is NOT that they were able to leave the USA - that is explained (it's still not possible, but in the context of the show and the suspension of disbelief we are meant to believe it) the mistake is that they are on the way back to the airport to return. That's absurd. They would have been under no illusions as to their banned status re reentry to the USA.
Anti-Thesis - S2-E3
Character mistake: Nicole Wallace has murdered and stolen the identity of Professor Elizabeth Hitchens, who was Australian. While speaking to Detective Goren she refers to her life in Melbourne, pronouncing it the American way : "Mel-born." No Australian would do such a thing - it is pronounced "Melbun." A detail-obsessed knowall like Goren would pick up on that immediately.
Visible crew/equipment: When Nina's just been shot, and makes it to the barn to call CTU (around 7.10am), while she's speaking on the phone there's a cameraman visible on the right hand side (DVD). (00:12:40)
Plot hole: Hippolyta tells Hawkgirl of Aresia's background of being born in the outside world, the war in her country and right up to her drifting to the shores of Themyscira. It would be impossible for her to know anything of Aresia's background as in part two, it's explained that the captain of the ship who saved Aresia died shortly after reaching Themyscira and therefore would not have been able to tell Hippolyta anything.
Character mistake: Previous episodes have established this story arc to be occurring in the year 2154. Yet here, when T'Pol records her log, she cites the date as 2152. (00:32:00)
She's Leaving Home, Bye Bye (1) - S3-E1
Continuity mistake: In this episode, it shows Brock and Reba moving into the house the show is set in and Kyra is mad about it. In episode 1-22, Reba flashes back to Cheyenne in the same house much younger than Kyra going into kindergarten. The houses should have been different.
Continuity mistake: In the movie "Channel Chasers," when Timmy and Vicky go into Maho Mushi, Timmy gets a piece of his hat sliced off and Vicky gets the tip of her ponytail sliced off. But in the next shot, they're both back to normal.
Continuity mistake: Dr. Cox's hair colour and length change back and forth significantly during the episode.
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.
Factual error: In this episode we see Blithe get shot in the neck and are told that he died in 1948. In reality he was shot in the shoulder and survived. He later served in Korea and was promoted to master sergeant as well as receiving the paratrooper of the year award. Blithe died in 1967 while on active duty in Germany.
Other mistake: Michael is 40 in Season 2 ep. 20 (Papa Said Knock You Out) while Jr. is 16 in ep. 19, which could not be possible since he had him when he was 16/17ish himself.
Plot hole: In the start of season 4 we meet Liberty's little brother, Danny. J.T. and Manny are making fun of him because he is new to the school and is starting out. If he is starting out, then he should be in the 7th grade, because it is stated in the first episode that the school changed into a 7-12. Liberty, J.T., Manny, Emma,Toby etc. are all in the 10th grade so how does it end up that Danny is a grade below Liberty?
Night of the Day of the Dead - S1-E24
Continuity mistake: At the Halloween party, after Lizzie notices the bride and groom dolls disappear from the table, the items around the space where they disappeared completely change between shots. (01:20:00)
Factual error: Aetius' troops don't look anything like 5th century Roman soldiers. They are carrying a large rectangular shield, a pilum (a spear which was used for throwing) and a sword (gladius) on their right. This was typical for the Roman army until about the 3rd century A.D. In Aetius' time, the soldiers would have had smaller oval shields, a hasta (a lance used for stabbing and for fending off cavalry attacks) and a sword (spatha) on their left. Also, there would be an enormous amount of "barbarian" mercenaries in the Roman army (Goths, Vandals, even Huns.), so it was hardly a Roman army anymore. And where's Aetius' cavalry?
Other mistake: At the start of the line dancing scene where Ray Von is deejaying, if you have the subtitles on, it says the song is Hillbilly Rock, Hillbilly Roll by the Woolpackers. It's actually 5,6,7,8 by Steps. (I'm quite embarrassed I know that).
Continuity mistake: During the scene with the family in the living room and Claudia and Lily are sitting on the covered couch, the sheet falls off the top of the couch. In subsequent shots the sheet falls off and goes back on the top through the whole scene.
Continuity mistake: Between the pilot episode and "The Terror" (which was never shown on TV), the costumes of Batmanuel and Captain Liberty change substantially even though there is no more than an hour between the events of the episodes.
Dirty Pool - S1-E14
Continuity mistake: When Tess is stuck in the mud with her car and Alex is helping her to get out, during their "fight" the mud on Tess' blouse changes a lot.
Suggested correction: Not everyone who is Australian says 'Melbun' when referring to Melbourne.
Utter rubbish. I lived in Australia for thirty five years. Nobody - absolutely nobody - calls it "Mel-Bawn." It's "Melbun." Incidentally, this also applies to the American pronunciation of the capital of Queensland - "Bris-bayne." It's pronounced "Brisbun."
