Deliberate mistake: During the scenes where Maverick is flying the Darkstar spy plane, his helmet is lit up on the inside, so we can see his face. In reality the light would be reflecting off the plexiglass, meaning we would not be able to see his face, and he would not be able to see at all.
Deliberate mistake: The baddies somehow manage to place the net under the two humongous ships by simply digging with their shovels in a matter of minutes, when they would need a bulldozer and several hours instead.
Deliberate mistake: Considering the position of the surveillance camera (height and angle - almost parallel to the side of the building as well as to the sidewalk), plus the lens being indented within the outer frame, it would not have been able to capture a view of Redd on the sidewalk below like it did.

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.

Deliberate mistake: Four hungry wild dogs are biting/eating at Virgil's abdominal area for some time, yet when the body is shown, some intestines are on top of his seemingly still-intact stomach - little, if any, of Virgil can be eaten by the "ravenous" dogs despite the length of time they are there. (01:29:00 - 01:30:13)
Deliberate mistake: At the end of the car chase with Penguin Batman's car drives upon a ramp at high speed before the explosions occur but his car only appears flying through the air and landing 15 seconds after the explosions. That's quite a long jump. (01:23:33)
Deliberate mistake: The decaying tree trunk would have more than likely broken into pieces and/or uprooted from the force exerted by the rope tethered to the pulling Parasaurolophus when Owen wrapped the rope around the trunk to stop the heavy-weight dino, but the trunk held up without even losing a shred of bark. (00:08:36)
Deliberate mistake: A camera situated behind a front passenger seat of a vehicle could not capture a clear image of the front seat passenger's face (James') in the rear view mirror and then slightly alter its angle to capture the driver's (Mike's) face in the same rear view mirror. (00:21:25)
Deliberate mistake: Due to some unknown factors (e.g, time of night), the doves' or pigeons' behavior in the boarded-up building falls short of "factual errors." Doves respond to sound and movement, so would have flown to higher spots when Alex was at the door. Doves typically roost up high, so it is questionable why they were at floor-level. If/when doves do sleep on/near the ground, they do so in a lighter mode (one eye open) and, when spooked, would have flown away at roughly the same time, not at intervals. (00:51:15)
