Revealing mistake: While Poe leads the aerial assault on the oscillator, in the closeups of Poe and other X-wing fighter pilots, note the cockpit windows at the pilots' left and right have identical marks and scratches in their individual X-wings. It's particularly noticeable when one closeup follows another.
Revealing mistake: When Benji imagines putting on a mask of an agent he plans to impersonate, when the camera pans around to first show the mirror, the mirror Benji's hands are further up on his face than the reflection, and the mirror Benji's hands move down his face slightly before the reflection starts to move them. Also, the mole that Ethan has on his left cheek isn't reversed in the mirror image. The "mirror" was actually a hole in the wall between two identical sets (one mirrored), with Simon Pegg and a Tom Cruise double in the foreground, and the mask actor and Tom Cruise in the background "mirror" set.

Revealing mistake: Inside Jurassic World's main control room, Chris Pratt looks at a view screen depicting a paramilitary team tracking down the escaped I-Rex. In an homage to the film Aliens, the screen is complete with POV cam footage and heart rate monitors. Unfortunately, the FX team didn't catch the fact that all four people are shown having identical heart rates. Ridley Scott made the same mistake in Prometheus. (00:44:00)
Revealing mistake: When Captain America is fighting Ultron in the truck, for a brief moment you can see a safety line holding actor Chris Evans as he's hanging on the side of the cab of the truck.
Revealing mistake: When Imortan Joe's body is thrown from the car by Max at the end, if you look closely when the crowd rush in it's just his costume there and no body.
Revealing mistake: When the semi trailer is coming at them sideways down the highway, the trailer is missing 4 wheels. The tandems do not have their inner dual tires on them. Perhaps this made it easier to slide the trailer sideways.
Revealing mistake: When Mark builds his HAB greenhouse, he surrounds the growing area with sheet plastic. Later, when making his first attempt at lighting the hydrogen to produce water, there is a small explosion, which throws Mark back across the HAB. Given that an open-air explosion will produce a 360 degree shock wave, there should have been a noticeable disturbance to the plastic sheeting throughout the HAB, but the only disturbance we see to the plastic sheeting is the location where Mark is blown into it.
Revealing mistake: When a force 10 gale is blowing and the CGI snow is horizontal... ... none of the trees move one bit, not one.
Revealing mistake: When the Nazi doctor starts to torture Solo in the electric chair, he turns off all lights in the room except for a single dim light bulb over Solo's head; so, we know that the background is uniformly dark. Moments later, when Ilya comes to the rescue, a lighted control room appears behind the doctor, off to one side. After they strap the Nazi doctor into the electric chair, there is now a lighted control room directly behind the chair.
Revealing mistake: When Verdean is scrolling the Wikipedia page for the Israeli wrestler "Johnny Jerusalem", the page itself is a well thought out fake one (the wrestler in question is non-existent), but the prop person who made this fake did not bother going all the way through editing the wording of the footnotes ("References" paragraph), that display instead the name of the real wiki page they edited as foundation. The webpage is an edit of the real Wikipedia page of The French Angel, the real life pro-wrestler who was also rumored to be an inspiration for the look of cartoon orc Shrek. All the names and dates have been slightly altered ("Paul Blowzier in New York" instead of Paul Bowser in Boston, "Carl Pohiello" instead of Karl Pojello, etc). (00:37:20)
