Continuity mistake: When Marlon stocks the vending machine, the camera (inside the back of the machine) shows him stocking the 1st row with brown-wrapper candy bars. He starts stocking the 2nd row with yellow-wrapper bars; Truman interrupts him for a minute (during which Marlon doesn't touch the bars at all). When Marlon continues, the yellow bars have changed to something darker (it's not just a different camera view; even barcodes are different). After another brief interruption, Marlon continues again, and the yellow bars are back. (00:35:00)
Continuity mistake: When Truman is going mental, with his wife in his car and they are about to go around the circle loads of times, it shows a shot of the car from the back. If you look at his wife's seatbelt it is on. However, a couple of seconds later it has another rear shot of the car and you can see the wife putting on her seatbelt again, when she already had it on. (00:48:00)
Continuity mistake: When the fallen lamp has settled, the glass and parts of the housing are in the sunlight, and the light is in the shadow, with the camera looking into the side of the shadow. As Truman comes out to investigate, the light has been turned to a new direction, the pieces of the housing are missing, and the glass is splayed out a lot more than it originally was.
Continuity mistake: In the scene where Truman is on the boat, it shows a shot of him wearing a green shirt and black trousers but in the next shot he is wearing a blue shirt and khaki trousers.
Continuity mistake: When Truman meets his father on the street, the father turns his head and looks at his son. The angle changes and his head repeats the movement. (00:15:10)

Continuity mistake: When the lamp is about to fall, the aerial view show a very simple street. From street level, the place is filled with all sorts of decoration. (00:03:15)
Continuity mistake: When the lamp falls, an aerial angle shows that the street is in the shadows. In the following angle the street is sunny. (00:03:15)
Suggested correction: As the lamp hits the road, the shadows of the houses and posts are regular. When the angle changes to look at Truman from between the posts, the shadows haven't changed. Only the angle we're looking at him, and so the angle we see the shadows.
Continuity mistake: The FM LED on the car's radio appears in the outside shots but disappears when seen from the inside of the panel.
