Other mistake: During an argument, Maggie's father mentions the border wall being built to keep people from entering the country illegally. This is obviously a reference to the real-life presidency of Donald Trump, but within the show's continuity, his comment doesn't make sense: in "Resist", the penultimate episode of season two, it's revealed that President Olivia Marsdin is literally an alien from outer space, and earlier in the season in "Welcome to Earth", she signed an executive order offering aliens such as herself full citizenship if they so desired it. If she's that tolerant of extraterrestrials, it seems unlikely that she'd be so intolerant of foreign immigrants as to resort to such an extreme action in foreign policy like building a wall on the border.
The Marriage of Lupin III - S1-E1
Other mistake: Rebecca drinks a very rare and prestigious wine; one wonders if part of its uniqueness lies also in the fact that according to its label it is a "Grand Vin De BARDEAUX", instead of Bordeaux. It is even a geographical name, not a trademark. (00:16:30)
Die Glocke - S4-E6
Other mistake: When Jones is trying to convince Herr Waesch that she's the owner of the estate where his gala is being held, subtitles of his reply read "I personally procured this home. It's owners were French." The contraction "it's" should be the possessive "its."
