The word "Fuck" is said 422 times, including in the narration - 2.4 times per minute on average.

Sharon Stone spent many long workdays in agony while filming scenes for this film. She has back trouble due to an old injury, and the gold & white beaded gown she wears during a casino scene weighed 45 pounds.

Madonna, Nicole Kidman, and Michelle Pfeiffer were considered for the role of Ginger. Melanie Griffith was almost cast, but Sharon Stone convinced director Martin Scorsese to give her the role.

The blackjack cheats were using a technique known as "spooking". It is highly illegal.

According to Alan King, Frank "Lefty" Rosenthal, upon whom the Robert De Niro character was based, wanted Richard Widmark to play the lead in the film. However, Widmark was 80 years old by that time, and, therefore, not a practical choice.

The blackjack cheat who gets away with the "warning" and is credited as Winner in the closing titles is played by Associate Producer and First Assistant Director Joseph Reidy.

To avoid the continuity problems that accompany a chain-smoking movie character, Robert De Niro always held his cigarettes the same distance from the lit end so that their lengths never appear to change.

The jewelry store owner who gets robbed by Nicky's boys is an actual Las Vegas jeweler. His line "I just got a shipment of diamonds from Israel" was not in the script.

Martin Scorsese stated before the film's release that he created the "head in the vise" scene as a sacrifice, certain the MPAA would insist it be cut. He hoped this would draw fire away from other violent scenes that would seem less so by comparison. When the MPAA made no objection to the vise scene, he left it in, albeit slightly edited.

The character played by Joe Pesci, Nicky Santoro, was based on the real-life gangster Tony "The Ant" Spilotro.

Cameo: [Frank Cullotta] the grey-haired hitman in sunglasses near the end of the movie. He was the chief lieutenant of Tony "The Ant" Spilotro in the late '70s, early '80s. Cullotta entered the Witness Protection Program before the "cornfield incident" took place and was not present, unlike Marino.

The scenes outside the fictional Tangiers was filmed in front of the Landmark Hotel across from the Las Vegas Hilton, the Landmark was imploded shortly after filming.

Casino was filmed entirely in the Las Vegas Valley. The casino and office scenes were filmed in the famed Riviera Hotel and Casino on the Las Vegas Strip and the driving scene in the beginning of the movie was filmed on Fremont Street in Downtown Las Vegas, which is no longer open to automobile traffic.

In Goodfellas (1990), Joe Pesci played character named Tommy DeVito. This the same name as the actor who plays the crooked poker dealer.

The character of K.K. Ichikawa (Nobu Matsuhisa), the Japanese highroller, is based on the life of high roller Akio Kashiwagi. During the 70's and 80's, Kashiwagi was a big scene at Las Vegas casinos. By the end of the 1980s, however, Kashiwagi had used up his casino credit, owing many casino executives, among them Donald Trump, millions of dollars. He was murdered in his home in Tokyo by the yakuza (Japanese mafia) in 1992.

The casino scenes were shot at the Riviera between 1:00 am and 4:am so as not to get in the way of the real gamblers. Although the casino didn't want the shoot to interrupt its business, that didn't prevent it from trying to lure more punters inside by putting up a large banner that said, "Robert De Niro, Sharon Stone, and Joe Pesci Filming the New Movie 'Casino' Inside!"

Martin Scorsese hired actual parolees from that era as plot consultants, as well as various F.B.I. agents who had busted same parolees.

"Ace" Rothstein's vehicle during the bombing scenes is a 1981 Cadillac featuring the ill-fated "V 8-6-4" engine. Offered for only one year, the engine was meant to save fuel by shutting off unneeded cylinders. This can be seen in the dashboard shot of the "MPG Sentinel" and its "Active Cyls" button at the end of the movie.

Continuity

When Nicky, Frank Marino, Jennifer are in the kitchen after they return home from their flight, Nicky makes Jennifer turn her head upside down to have the diamonds he stole & smuggled through airport security fall out of her hair up-do onto the table. After all they all fall out, her hair "bun" releases and is hanging down in an undone, long ponytail. But immediately after that shot when the camera switches angles, Nicky slaps her on the cheek and her hair is back up in a bun the way it was originally.

SPOILER. As Nicky and his brother are being buried in the desert grave, Dominick is dumped into the grave first and lands on his right side, facing right. The next time we see him, moments later, he is lying on his left side, and facing left as Nicky is dumped on top of him.

After Nicky has stabbed the man with the pen in the bar, he puts the hand that was holding the pen up on the bar counter. Although, the pen that was in his hand had been covered in blood, his hand is clean.

After being chastised by his mother, Piscano backs into a display of olive oil, displacing some bottles. In the next shot of them, they are perfectly arranged.

When Sam introduces Nicky to the casino manager, he stands up twice.



Factual errors

After the failed car bombing, Sam is put into the ambulance feet-first. People are loaded into ambulances head-first, since most of the monitoring equipment is in the front.

As Philip Green is coming off the plane and is being questioned by the press about Anna Scott's murder, one of the cameramen (the one who walks in front of the movie's camera) is seen carrying a camera not connected to anything. That model of camera (the RCA TK76) required an external tape deck/battery pack, otherwise the camera wouldn't function at all. The other two cameramen in the scene have their cameras tethered to the external equipment.



Incorrectly regarded as goofs

Don Ward, the fired overseer of the slot machines, is said to be the county commissioner's cousin, but later is said to be a brother-in-law. These terms are not mutually exclusive - his "hillbilly" accent makes it even easier to believe that he can be both.

When Nicky shoots the lady in the kitchen his arm is placed directly in the gun's aim and is not hit by an exiting slug. However, since the bullets were .22 caliber, and quite likely shorts, they likely never exited the skull.

Nicky says "...meet me a hundred yards down the road". Ace narrates: "...when I heard him say a couple hundred yards down the road..."



Revealing mistakes

Obvious dummy in the car immediately before the explosion.

Wrist pads visible on Ginger when Nicky throws her out of the restaurant.

Just before Ace's car explodes, his narration says the dynamite was placed under the passenger's seat. Yet when the explosion occurs, it is the engine compartment that blows up first.

When the card cheater gets his hand smashed with a hammer, at first he doesn't flinch or move his hand in any way and his fingers are widely spread. The camera changes angles and now his fingers are spaced closely together and he's wiggling them. From this angle, the security guard delivers one more hammer blow but it is actually off to the side. For the first cut, they must be hitting a prosthetic hand with spread fingers since it never moves. For the second, they then bring the actor's actual hand in but keep his fingers tight to avoid accidentally hitting them.

During kitchen scene in Leaning Tower restaurant near end of film, frosty breaths of Nicky and another character are clearly visible, indicating scene was shot on unheated location set - functioning restaurant kitchens are always hot.



Miscellaneous

Although this is refuted, the scene where Nicky murders witness Anna Scott should be considered an error. His arm is on the other side of her skull in the line of fire. How a professional assassin would KNOW that the bullets wouldn't exit into his arm is ludicrous. No experienced killer would take the chance. The writer says they were likely short bullets, but there is no basis for that conclusion.

During the scene where the cowboy is exited out of the casino headfirst by the security guards, one of the guards hits his head on the door frame.

At 47:14 when exiting the jet in Los Angeles, Sharon Stone stumbles slightly when her boot heel catches on the first step. The viewer might assume that the character was on drugs at the time, but no other indications of that are present.

As Nicky Santoro (Pesci) was was heading out to the desert to meet Sam with multiple car changes, the unseen FBI agent says "OK, he's out. It's the ant. Brown unit." Nicky Santoro is based on Anthony "the ant" Spilotro in the book, but should never have been called the ant in the movie as his name was changed.

The cowboy who discusses his cousin's firing with Deniro, wears a huge turquoise bolo tie that's later worn as a necklace by Ginger when she exits the courtroom with Deniro.



Anachronisms

In the first newscast scene, before Ace's license hearing (which takes place around 1980), the Mirage hotel and casino can be seen in the background shot of Las Vegas. The Mirage was not completed until 1989.

When Ace and Nicky take a drive around Vegas after Nicky first arrives in town, there are several modern vehicles visible on the streets around them.

The shots of "The Stardust" and the entry to "The Flamingo" show the results of redesigns done in the early 1990s.

The Budweiser bottle the cowboy (with his feet on the table) is drinking is of the modern (1995) model and not the correct 1970's style.

A close-up shot of silver dollars in the beginning of the film reveals a bicentennial silver dollar, released during the years 1975-1976. The film's beginning takes place in 1973.



Audio/visual unsynchronized

The sound of shoes walking on floor is heard in the bedroom when Ginger returns to Ace after he throws her out of the house. The bedroom is carpeted, so Ginger's shoes shouldn't have made any sound.

Nicky squeals the tires of his car in the dust in the desert.

When Ace and Sherbert are entering the car to chase after Ginger, the car starts up before Ace is even in the driver's seat.

In the scene when Nicky and Frank collect from the bookie Frank points and says "smarten up," but his lips don't move.

in the scene where Ginger and Sam/Ace are at dinner at a restaurant, the camera keeps switching back and forth to Ginger and Ace, when the camera is looking at Ginger, Ace is talking to her, but he is not moving his mouth.



Crew or equipment visible

Camera crew can be seen reflected in car door as Nicky opens it when driving up to meet Ace in the desert.

As Ace drags Ginger across the living room floor, a quick reflection of the "steady cam" crew following the actors can be glimpsed in a large mirror off to the viewer's right.

As Sam walks towards the car that will catch fire, the cameraman is reflected in the driver's side window.

As Sam meets Commissioner Webb in Sam's office, a faint reflection of a crew member can be seen in the window on the left.

Reflected in the passengers side of Sam's Cadillac's door as he pulls up to the new house with Ginger after they get married.



Errors in geography

When Nicky first comes to town, Ace shows him the panoramic daytime view from his corner suite. The only high rise building that can be seen is the Landmark (demolished). Later, in the scene where Ace proposes to Ginger, the same view, at nighttime, is instead filled with high rise buildings as well as nearby Dunes and Frontier marquees. The nighttime view is clearly fabricated; the south-Strip Dunes (demolished) is nowhere near the north-Strip Frontier (demolished). The daytime view implies the corner suite is somewhere inside the Las Vegas Hilton.

During car ride where Nicky is discussing possibility of moving to Las Vegas with Sam, scenery outside window flip flops wildly from shots of downtown Vegas to scenes of miles-away Vegas Strip.

The film takes place in the (fictional) Tangiers casino, but in one of the scenes in Robert De Niro's character's office, you can clearly see a calendar for the Riviera (the movie was primarily filmed in the Riviera.)

When Ace and Nicky are supposedly driving in Downtown Las Vegas, the view differs from each of their side windows. The Fremont Hotel is visible out of one window, and the Sahara out of the other. The Fremont is on Fremont Street, while the Sahara is on the Las Vegas Strip.



Plot holes

Seeking a place where they can converse without being overheard, Ace and Nicky go into Ace's closed up home garage, start the car engine, turn on the radio, and engage in a long conversation. The carbon monoxide fumes from the car engine would have soon knocked them out and killed them.

After Sam has the cowboy thrown out, Nicky calls him, at which time Sam tells him that the cowboy had insulted him. When Nicky gets off the call, he yells at the cowboy for putting his feet on the table, yet Sam never said that in the call.



Boom mic visible

When Ginger enters the bank, the boom mic is visible on the window door right above her head, but only for a brief few seconds.



Character error

Before smashing the cheater's hand with the hammer, Ace says "I saw you shuffling your chips with your right hand. Can you do that with your left?" and the cheater responds by saying he'd never tried. Both men are incorrect. The cheater was shuffling the chips with his left hand all along because he was using his right hand to tap out signals to his partner.

When Nicky murders Anna Scott, he isn't wearing any gloves, so in addition to placing his hands on her head and doorknob and whatever else, he's leaving fingerprints all over the place.

When Pat Webb is meeting with Ace to ask for Don Ward to be rehired as the slots manager, Ace responds that Webb's accusation is "libelous." For Webb's comment to have been "libelous," it would have had to appear in print. Ace should have said that Webb's accusation was "slanderous."

When Lester calls Ginger after her wedding, he says he always remembers her as a "long-legged little colt". A colt is a younger-than-4-years MALE horse. He should have called her a "long-legged little filly".

In voiceover, Ace says that to go anywhere, Nicky had to change cars 6 times in underground parking garages. But in the accompanying visual montage, all of the garages we see are aboveground (evidenced by the bright sunlight on the sides).
