Revealing mistake: After the sniper is shot he falls through the wall. Look at his silencer when he hits the ground - it bends where it attaches to the muzzle. A real metal silencer wouldn't do that. (00:41:25)
Revealing mistake: Just before Marguerite tastes the chocolate Henry gives her, in the shot of the group walking past a pen of geese, the modern, flat, white soled shoes (likely canvas sneakers) the sisters are wearing are visible as they walk. (00:51:00)
Revealing mistake: When Wade gets shot, watch the shot where Upham brings the bags up to the injured medic. The next shot there is some fog which then reveals the injured medic. In this shot, watch carefully as the cast rips away the medic's shirt. If you look near the neck, you can see the fake stomach vest he is wearing for a split second - when the actor realises he ripped too far up, he quickly covers it back up. (01:28:43)

Revealing mistake: Near the end of the film, after the shootout, there's a shot with the camera zooming in on a newspaper at Will Smith's front door. If you pause it right once the headline fills the top of the screen, you'll notice all the paragraphs are just repeated, word for word. Additionally the word "received" is misspelled.
Revealing mistake: When Truman is first discovered escaping on the boat, they go to a camera shot of his face. If you look at the water, the boat is not moving at all. They use a similar shot later in the scene after the storm. You can also tell the background is the same as the large wall that Truman crashes his boat into. (01:19:05 - 01:25:25)
Revealing mistake: Right at the start there is a TV 'clip' showing the crowds outside the Lyceum. This is supposedly 1974 but you can quite see a pretty modern looking CCTV camera above the Lyceum door.
