Revealing mistake: When Han shoots at Bruce Willis and the others with the Gatling gun, we see cartridges on the ground. You can tell that they are all blanks. The tip is jagged and has been closed - live ammo just has an open hole where the bullet was.
Continuity mistake: During the chase scene on the bridge involving the tank, two cars (silver Toyota Corolla hatchback, licence NE34 12 and a black VW Bora, licence NU67 67) appear during many shots, often travelling in different directions on the bridge and either ahead or behind the chase.
Continuity mistake: When Teresa is yelling and hitting Jordan because he cheated on her with the blonde girl in the limo, the car disappears and reappears between shots. (01:00:35)
Plot hole: Each of the four magicians are given a tarot card that has a date (March 29), a time (4:44pm), an address (45 East Evan St), and a city (NY). When they enter the building on that date, they know which apartment to go to. The problem with this is that it was never stated on any of the cards which apartment to go to once they reached 45 East Evan Street. (00:08:40 - 00:10:05)
Character mistake: In the scene where Nicki is being interviewed by Vanity Fair, she refers to her younger sister, "Gabby." Nicki is the character based upon Alexis Neiers. In the movie, her younger sister's name is supposed to be Emily. Gabby is the real life name of Alexis' younger sister.
Continuity mistake: When Sandy takes a taxi and goes to Diane's house, as he is arguing with her, the sweat pattern on his shirt changes several times as the scene switches from him to her and back.
Continuity mistake: In the shot where Holly is done injecting Anna with the syringe and stands up to shoot at Detective Loki, the syringe and two "medicine/poison" bottles are all close together next to Anna's hair. Next three shots showing the room far out with Holly getting shot and killed has the two bottles next to the edge of the rug and very far from Anna's hair, as well as the syringe which is slightly closer, but far away. The next shot of Loki picking up Anna has the syringe and bottles in their original position next to Anna's hair.
Continuity mistake: In the scene when Yuri's daughter is getting away from the hotel, the color of the chopper changes from green to brown between shots.
Factual error: When Bradley Cooper calls Louis C.K. he asks him, "Where are you?" Given he's just called him on his office number, rather than a carphone, he knows exactly where he is.
Continuity mistake: While Shannon and Sarah are speaking to Robin, two people (a blond white guy and a black guy with a blue satchel) pass by the trio twice.
Other mistake: When the driver of the ZR1 corvette changes gears the emergency brake lever is visibly up. (00:53:00 - 00:53:55)
Plot hole: They discover a "not so well hidden" microphone in the car that tells them the "man" is listening to them, but it is ignored throughout the rest of the movie, especially when setting up a video loop to cover their extracurricular activities. (00:30:00)
Audio problem: When Hayes and Nick are fighting at the end, Hayes grabs Nick and says "get over here", but his mouth never moves and his teeth are clenched the whole time.
Revealing mistake: At the end of the film when John Moon is digging a shallow grave for the dead girl (who has been dead for days, and spent additional days in a freezer also). You can see the dead girl breathing by the way her arm is moving on her chest. (01:46:00 - 01:47:00)
Continuity mistake: In the scene when Papi is in the back of the white Fodge driven by Stig, the Ford Bronco driven by Bobby crashes into Stig's white Dodge twice - both headlights are smashed out. Once the Bronco goes into the ditch and comes back out, the passenger side headlight isn't broken.
Visible crew/equipment: After the jewelry heist, outside in the backyard when Ross looks for Parker, the camera crew is visible through the window, about three or four shadows appearing on the window reflection. (01:42:35)
Factual error: In a scene where the nightclub singer with the tropical fruit headwear is on stage, she is singing into a classic RCA 77D microphone which is correct for the period, but in a mistake often made in movies that are set in this era, the microphone is wrongly positioned. It is leaning toward the singer when in fact this type of mic is spoken to from the side, not the end. To work correctly it was always pointed away from the singer or placed in a vertical position for side pickup. (01:06:15)
Continuity mistake: When Dave is shot by Mindy while training, there are two bullet holes in his jacket when he has only been shot once at that point.
Character mistake: In the scene where Billy is called to the crime scene of Andrews' murder, Andrews' body is shown with a wound on his chest. Later in the movie though, Billy is questioning Todd Lancaster. Todd Lancaster says that he saw Andrews get shot in the head. (00:52:00 - 01:25:00)
Continuity mistake: The Counselor's watchband during the long phone call about choices, fate, and grief with Jefe changes the direction in which it is latched several times throughout the scene. It is quite prominent because it is on the arm he is using to hold the phone. (01:35:00 - 01:40:00)
