Deliberate mistake: When the gangs meet in the toilets to set a date for the brawl, the mirror on the left is the only one opaque, most surely to avoid reflections of the filming crew.
Deliberate mistake: An LAPD cop discharges his firearm a full size Glock which has a minimum magazine capacity of 13+1 for the Glock 21. The Glock 21 is approved LAPD issue along with other variants. He fires maybe three shots and the slide locks back signalling that it's dry. A second later the same cop is walking with the same empty Glock aimed towards the suspect which was shot at. It's visible that the slide is being held back by the slide stop since the magazine went dry. (01:29:58)
Deliberate mistake: In all the shoot-outs, the bullets that hit the cars spark, which bullets do not do, and leave no hole, dent, or even a small scratch. They do, however, break the glass.
Suggested correction: This isn't correct. In the big shootout towards the end, gunshots leave holes in car doors and break car windows from both sides of the fight.
Deliberate mistake: When Brian and Bilkins are at the demolition derby, Roman wins and gets out of his car. As he scans the crowd, he sees Brian. When we see Brian the logo on his shirt has a 3D effect to it that goes back and to the left. In all other shots of that logo, the effect goes back and to the right. This shot is reversed.
Deliberate mistake: Denzel Washington never wears a vest (at least during the previews). All deputies are mandated to wear at least a level II vest (most will buy a higher protection vest) whenever performing Sheriff duties. Plus his duty shirt is just plain sloppy looking, way too big for him.
Deliberate mistake: In the opening scenes just after the restaurant dialogue, as soon as the scene changes there is a quick cutscene which shows the screen zooming in on the Pentagon. If you look In the lower left corner, the text on screen gives the Pentagon location as being in Washington D.C. however, The Pentagon is located in Arlington, Virginia. (00:19:02)
Deliberate mistake: A branding iron loses its bright orange glow relatively fast when it's out of the fire. When the police enters the room it is still very bright orange even though it has been on the floor for some time.
Deliberate mistake: Perhaps to avoid getting an R rating or parental complaints notice how in the operating room massacre none of the doctors appear to bleed nor do Doc Ock's tentacles have blood on them.
Suggested correction: The problem is in both versions of the film, basically all of the deaths either happen off-camera, or are things like people being shocked to death or killed by being tossed around and presumably having their backs/necks broken. Most of the deaths would be bloodless or near-bloodless anyways, and the camera simply doesn't linger on the bodies enough to show any blood. This is also why the tentacles aren't really bloody. Sure, it was probably ratings-related, but it isn't technically a mistake.
Deliberate mistake: When the inmates first leave their cells we see at least 2 that have white or light colored shirts on instead of prison blue.
Deliberate mistake: When the people come into the club looking for money off the owner a fight breaks out between the Krays and the people the Krays stick a sword through the gang leaders hand. But it quite obviously goes through the gap in his fingers. (00:35:10)
Deliberate mistake: The view looking out the windshield showed the man on the bicycle had stopped when he was in front of the car's passenger side, but the outside view showed the man still coming to a stop and then tilting his bicycle. (00:07:12)
Deliberate mistake: A car plummeting 10 metres off from a plane, landing on two cars as if they were a pair of soft gymnastics pit mats, just to keep on driving without a single scratch - let alone a mechanical breakdown or the blowing up of a tyre - defies all laws of physics and common sense.
Deliberate mistake: Carson's [John Travolta] cat Raymond did not appear to be in the pet carrier when he was running out of the building to his car or when walking to his office and placing the carrier on the desk. (00:02:15 - 00:03:30)
Deliberate mistake: In the scene where Mindy saves the dressed-up Dave from the street thugs and almost gets caught by the police. The female voice over the police radio remarks that the suspect is "under five feet" (below 152 cm). As she flees, she uncovered her motorcycle which appears to be a Ducati 1199 Panigale. The Panigale has a seat height of 82.5 cm, which means that by proportion, Mindy cannot sit on the bike with both feet flat on the ground (as a comparison, I'm 5'9 / 175 cm and still have to tiptoe a little bit on the Panigale, so even if she's slightly taller she still couldn't). Yet in the end scene where Mindy drops Dave at home after the final fight, she seems to be able to sustain the bike with both feet only slightly tiptoed, although her boots are not that tall. (00:13:20 - 01:34:30)
Deliberate mistake: Although much of Auto Focus revolves around the 1960s hit television series "Hogan's Heroes," the producers of this independent film could not work out a licensing agreement with CBS regarding the famous "Hogan's Heroes" theme music. As a result, the familiar "Hogan's Heroes" theme music is entirely absent from Auto Focus, replaced with contrived theme music that isn't even remotely similar to the original.
Deliberate mistake: Early in the movie someone fires an RPG, and, when he does, they show him comically being flung back through the air by some kind of supposed recoil effect. RPGs are rockets shooting out of tubes with the blast going backwards, so the holder of the tube themselves experiences no recoil.
Deliberate mistake: The thug wearing headphones and facing the money on the shelves did not notice that Savage forcefully opened the door several feet to his right, slamming it against the adjacent wall, or that Savage had entered the room. The bang to and vibration from the door hitting the wall should have been enough to overpower the sound from his earphones, but - even if they weren't - his peripheral vision should have sensed the door opening and Savage entering. (00:02:55)
Deliberate mistake: A shot of the pile of ashes from the fire wherein Cassie's body was essentially cremated showed Nina's half of the broken heart necklace sticking out ABOVE the ashes, which would be impossible. Also, a metal charm on a chain that was around Cassie's neck would not survive the huge fire or be totally clean and unscathed.
Deliberate mistake: At the end of the film, two officers attempt to surround and handcuff Joshua. Using two officers to cuff someone is NEVER done for the exact reason of what ends up happening, as Joshua manages to grab a gun from one of the officers. Only one officer would have been doing the deed in the real world, but it's clear this error in being completely against police protocol had to happen so the good guys could prevail over the villain.
Deliberate mistake: When the procession gets ambushed in the street by the guy with the automatic weapon, he shoots at the police cars. There are no drivers in the cars.
