Revealing mistake: When the elevator crashes, there's a really crappy splat of blood on screen that appears abruptly, which is a very obvious over-impression of a painting.

Continuity mistake: When Indy and Helena find the antikythera in Archimedes' tomb, it's covered in dust and no features are visible. When Indy reaches for it, it's just slightly dusty.

Sacha ★

Continuity mistake: When Lt. Snyder breaks the phone booth window with his gun and points it at Hooker, Hooker's hat falls off. Yet in the next shot over Lt. Snyder's shoulder you can see that Hooker's hat is back on his head.

Visible crew/equipment: When Robert Redford is being chased by Lt. Snyder, he jumps from a high place to the ground. One can easily tell it's not Redford but a stunt double.

Sacha ★

Continuity mistake: When Indy is shot, he falls with the strap of his satchel running down the side of his body. A shot later, he lies with the strap running across his chest. Then, a shot later, the strap is nowhere to be seen.

Continuity mistake: When the villains are following Indy through the caves, the old wooden bridge completely breaks and falls apart. However, when they make their escape across the same bridge, it's intact with only a couple of wooden slats broken.

Visible crew/equipment: When Logan is changing his shirt in his office and Blanchard steps in, lighting screens are reflected on his lenses all the time.

Sacha ★

Visible crew/equipment: When Logan and Laura exit the auction house, a camera or black piece of filming equipment is reflected on the window. Can't be a street sign because it moves all the time, and there is no sign next to the car on the opposite shots.

Trivia: If you compare both times that the signature on the painting is revealed (in 1968 and in 1985), you'll notice that the "b" in Sebastian Deardon is different. You have to pause and make a screenshot of both to spot it.

Continuity mistake: In the scene where he is fixing breakfast for his daughter, Robert Redford's shirt sleeves are down. When he goes to rescue the burning toast in the oven, his shirt sleeves are up and then they are down again. (00:15:00)

Continuity mistake: When Marty tells George how to flirt with Lorraine, they both enter the diner and Marty sits on the back of the counter but disappears between shots, only to reappear later on. Also, the extras around him change, although they're all dressed in similarly colored clothes. Check a man in a plaid jacket next to the blonde girl in pink, who disappears when Marty trips Biff. This continuity havoc was due to the combination of Eric Stoltz scenes and new Michael J. Fox reshoots.

Sacha ★

Continuity mistake: When Michael J Fox's parent kiss and the family picture (with everyone standing on the grass) gets fixed, Michael places the photo on the guitar, gets very happy and starts playing the guitar enthusiastically. Seconds later, a brief shot of the guitar shows the picture with Marty only, his brothers are missing. (01:26:18)

Visible crew/equipment: At the drive in theater, Marty says he'll put the boots on when he gets there. The camera pans to the left to follow Marty and Doc as they continue to talk. On the very far left side of the screen, the shadow of the boom mic briefly dips into frame. This happens just before Doc walks over to the DeLorean from his car. (00:16:35)

Visible crew/equipment: When Marty is with Jennifer in his new truck, as the camera cranes down to where they're talking, you can see a crewmember with a white shirt and some of the camera and crane. (01:46:10)

Continuity mistake: Watch as Seamus hands Marty the baby, there is a definite "jump" and Marty is facing in almost completely the wrong direction, looking for a clue from the set's crew as to where he should be looking to catch the baby from... (00:24:20)

Continuity mistake: Dan throws his umbrella and it bounces on the edge of the wastebasket but lands on the floor. When he walks next to the wastebasket the umbrella is now inside.

Sacha ★

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.

Sacha ★

Visible crew/equipment: When Simon and Katya are in the helicopter, both are replaced by obvious stunts. Simon has dyed blond hair as opposed to his brunette stunt, while she has short and straight hair, but her stunt's is long and curly.

Sacha ★

Revealing mistake: When Simon is in the helicopter and shoots at McClane, check the metal strips next to his feet and the protruding metal parts where the squibs have been placed to allow for the pyrotechnics.

Sacha ★

Continuity mistake: When Miguel is with the pedophile, he is given bread (or something similar) to eat. Shot changes, and the bread is suddenly bitten. The bread's length keeps changing several times between shots.
