Deliberate mistake: Driving to Malibu, Knox's truck is going the wrong direction on the road - the solid double yellow lines are on the passenger's side and the solid white line is on the driver's side. (The driver is on the left side of the vehicle.) There is no solid white line on the opposite side, indicating it is a one-direction road. The truck quickly crosses over the yellow lines and goes off-screen, after which it can be seen there's a wide paved shoulder that tapers to the edge near the intersection. (00:03:20)
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: Kurt was close to the passenger side when Malik shot him from the opposite side of the car, but he fell backwards some distance from the car (and not from the force of the bullet). (01:24:40)
Deliberate mistake: Evie digs a box out of the greenhouse dirt, but no dirt falls off the box, and the box is clean when she moves it onto her lap. (00:09:00)
Deliberate mistake: The Janitor was driving away from Willy's but the explosion shows up in the front of his sunglasses. (01:21:47)
Deliberate mistake: The F&F series always shows some amazingly advanced (and unlikely) technology; in this movie there is a big usage of electromagnets that are nothing short of miraculous. Not only they have a strength that would require them to have generators tens of times bigger than the cars they are on, and repel with the same ease as they attract; they also attract objects with varying° of precision and direction, all by turning their simple dial.
Deliberate mistake: Louis says to his opponent "Glock 17, 17 rounds." The opponent says back "I lost count." In modern semi-automatic handguns, especially Glocks, after the last round is fired the slide stays permanently open till a new magazine is inserted and slide is racked, or the slide stop lever is manipulated (depressed down). The slide can be closed on an empty magazine as well by the slide stop lever. (01:11:00 - 01:11:30)
Deliberate mistake: The Glock pistol the dying Russian assassin attempts to fire clicks, symbolizing it's out of ammo, or had a malfunction such as failure to ignite primer which is extraordinarily unlikely. His action symbolized a dry weapon. When a modern handgun in particular a Glock runs dry, the slide stop lever engages the slide and leaves the slide open until a new magazine is inserted and the slide is racked or the slide stop is pushed down. On a dry Glock the trigger can't be pressed until the slide is cocked. (00:16:45 - 00:17:30)
Deliberate mistake: When Kasady and his symbiote are fighting for control at the bell tower, they are reflected inside Venom's eyes...who is lying on his back in the middle of the cathedral and is nowhere near and at the totally wrong angle for a reflection like that to happen. (01:15:50)
Deliberate mistake: The Virtuoso (up several stories in a building) would not be able to hear what the boy and his mother across the street were saying. The boy even started to say "Hey, mom" when he was still exiting the building. (00:11:41)
Deliberate mistake: When James started to fall off the ladder, he tried to jump to reach the other side. Thom grabbed his right hand with his and was able to pull him to safety. James' weight and the force with which he jumped and swayed would have most likely resulted in James pulling Thom over the edge with him, and both being seriously injured or killed. (01:22:26)
Deliberate mistake: The "Sixth Street Coffee" surveillance video footage of Zara disarming the barista's determined ex-boyfriend was different from the actual event when shown on Audrey's cell phone (recorded from TV news). The most obvious difference was that Zara never held the gun with both hands behind her and making a circular motion over her head before aiming at the man she had kicked to the floor. (00:08:10 - 00:09:45)
Deliberate mistake: Nora's car smashed through the (almost floor-length) windows in the police station and exited the building airborne - and stayed airborne long enough to clear a police car parked alongside the building (or curb). (00:27:05)
