Revealing mistake: KantMiss puts the chicken badge in her sister's hand. Actually through her hand, since it stabs her with a long and sharp pin. But as she holds her hand, the long piece of metal is gone - it's perfectly fine for the characters to suddenly heal from one scene to another since it's a crazy spoof movie, but here we are midway through a visual gag and the nail is missing while the girl is still screaming in pain trying in vain to pull free.

Revealing mistake: When the 47 Ronin write down their names to swear fealty to the mission, they are cutting their thumbs on the swords to imprint their fingerprints on the document. The mistake is that they use the blunt edge of the sword to do this.
Revealing mistake: During the big shoot-out at the end, the close-up of the brown Ford pickup is flipped side to side. Check out the F150 logo on the fender, which appears as a mirror image.
Revealing mistake: When the kids are fighting and one of them puts the other in a Boston Crab hold, a third kid, the main character, breaks up the fight by, well, embarrassing to say, poking the assailant in the butthole with two fingers. Jo rolls away and keeps screaming indicating that he got hurt not just in his pride, but you could easily see that no such action was actually perpetrated. (00:19:15)
Revealing mistake: Whenever Ralph is driving Travers in the limousine and the exterior of the car is seen in a long shot, there is no one riding in it other than the driver. From every view point of the windows that can be seen, there is no passenger inside where Travers is supposed to be seated.
Revealing mistake: At the end when the drone crashes in front of the car and the soldier gets out you can see the footprints in the sand from previous takes, in the exact spot where he steps.
Revealing mistake: Not bad digital effects for a combination "Predator" and "Jurassic Park" monster movie, except that the dinosaurs don't cast shadows about half the time.
Revealing mistake: When Eliza is negotiating a deal to sell the pig to Magda whilst sitting at the kitchen table, Magda takes out her phone to call someone. When she puts the phone to her ear, a search bar and keypad can be seen instead of the call screen, revealing that she is not actually making a call. (00:28:30)
Revealing mistake: When Ginger and Augie get into the limo nearish the start, it's obvious the street has been closed for the filming of the limo driving down the street because the limo driver goes across a red light. You can't see the red light directly, but you can see the green light on the opposing street.
Revealing mistake: When Agnes slits Manny's throat, you can see the crease on the prosthetic part of his neck. And the blood flow looks totally fake. (00:37:45)
Revealing mistake: Pablo and his buddy are driving through the middle of nowhere, and end up in the bucolic town of Red Stone. The first two people they drive by are armed with machetes. The close-up of the second one is reversed, as shown by the dilapidated street sign - it can't be deliberately shown by say, the car mirror, because they are looking at him turning their head.
