Continuity mistake: When Indy is abducted during parade day inside the truck, his hairstyle keeps changing all the time.
Continuity mistake: The first post-credits scene is a total editing mess: Shazam blows up the second bottle. Then shoots a second time and the bottle magically reappears and he blows it up again. Shot changes and the first broken bottle has swapped sides with the beer bottle.
Revealing mistake: During the chase in Gotham, the armoured truck crashes against a jeep. The driver remains stiff as a board, unaffected by the violent impact or any laws of physics, revealing it's a dummy (or a CGI asset).
Continuity mistake: The two knives that Dante drops on the floor lie together in an L shape. A shot later, they're over a metre apart. (00:20:00 - 00:20:25)
Revealing mistake: While inside the tunnel in Rome, before the yellow Fiat makes a U-turn multiple skid marks from previous takes are visible. Though one might pressume that the marks were already there, they are at the same spot and have the same pattern as the skid marks that the cars make seconds later.
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.
Continuity mistake: When the Mafia boss dies, he falls next to a fruit stall. A crate falls next to his head, and fruit falls on the floor. When the shot changes, the crate has moved away, and the fruit has vanished.
