That recent QoD you refer to, for anyone who missed it, was about the legal and other possible pitfalls that can arise from using real locations in a fictitious work about Las Vegas (or any other real location), and your quote was in reference to some well-known movies we mentioned, which filmed on location in Sin City and which are all known for the odd reality-altering blooper when it comes to locations and continuity.
The 1971 James Bond classic Diamonds Are Forever, starring Sean Connery, filmed extensively on location here, making use of no less than eight real-life casinos (and many other venues). While critics have noted many little bloopers, it's pretty clean as far as the locations are concerned, with one notable exception. There's a car chase involving Bond and the cops that takes place downtown on Fremont Street (many years prior to it being pedestrianized), during the course of which 007 passes several famous casinos, notably the Vegas Club, Binion's Horseshoe, and the Golden Nugget, on multiple occasions -- and in both directions! -- without making enough U-turns to make sense and without making enough turns, period, to have been driving around the block. The whole scene seems to mess with the space-time continuum -- check out the link to see for yourself.
Casino is another movie that filmed extensively on location in Las Vegas and features several anachronisms, including upgrades to the facades of the Flamingo and Stardust that occurred in the early 1990s, although the film is set between 1973 and the early '80s. By the same token, in the first newscast scene before Ace Rothstein's license hearing (which takes place around 1980), the Mirage is visible in the background of a shot, despite not having been built until 1989.
While such anachronistic goofs are extremely hard to avoid when you're using a real location as a historical set, there are plenty of others that are simply down to continuity or ignorance/liberties taken in the cutting room. For example, there's a scene when Ace (Robert De Niro) and Nicky (Joe Pesci) are supposedly driving downtown, but while the Fremont is visible out of one window, the Sahara, which was located on the Strip where SLS now stands, is the view out of the other window!
By the same token, Ace shows Nicky the daytime view from his corner suite when the latter first arrives in town. It shows the now-demolished Landmark, which was across from the former Las Vegas Hilton. Later, when the view from the same suite is shown at night, it's a totally different view of multiple high-rise buildings, and defies geography by including the Dunes and the Frontier, although they were at opposite ends of the Strip (the former on the site where Bellagio now stands, the latter opposite Wynn/Encore).
Still, both of these movies are excused, in our book, since their geo-sins are pretty minor and it definitely adds to their authenticity and nostalgia factor by featuring real-life locations, a few of which you can still visit today, like the Peppermill (featured in Casino).
The final film in the trilogy we referred to, however, is a notorious turkey in every respect, and its location violations contributed to the lambasting it received from critics and the viewing public alike. This writer is happy not to have actually wasted any valuable life hours having watched the disaster flick (in every sense!) that is Con Air, so what follows is thankfully gleaned purely from other sources, but it's all very-well documented (no doubt to the director and editor's eternal shame.)
There's one scene in where a car enters a tunnel, apparently near the Strip, and magically emerge from the other end downtown. Not only is that a profound elongation of the McCarran bypass tunnel, but if that's what it's intended to be, the director was psychic, since that didn't even exist until a year after the movie was made! Still, that's nothing. It gets worse. Much worse.
As the plane is careening into the Strip in the climax, it passes/hits a multitude of casinos, in a very interesting order: It passes the Stratosphere and is heading south on Las Vegas Boulevard, but then hits the guitar of the Hard Rock Hotel marquee on Paradise. Next stop? Circus Circus! A few clips later, as it's about to touch down, it passes the faux wooden roller coaster that adorned the facade of the former Boardwalk Casino (where CityCenter now stands) and as if that's not bad enough, the casino is shown on the wrong side of the plane, meaning it's now miraculously headed north! Further confusion is evident, with juxtaposed views of Barbary Coast (later Bill's, now The Cromwell), the Mirage, and the Sands (now Venetian), where it finally comes to rest at the front door, we understand.
These location bloopers were the least of this movie's problems, however, with pretty much everyone who was associated with it counting it as one of the lowest points in their career (John Cusack categorically refuses to discuss it any interview).
If anyone in QoDland feels inclined to share any other similar Vegas-movie location bloopers they're aware of, feel free, and we'll add them as "Updates" to this answer.
