Revealing mistake: After jumping in front of the train, Clark runs leaving a white trace behind. Watch the grass on the lower right and you'll see the scene is speeded up.

Continuity mistake: When the player takes Susie with him, a bucket appears from nowhere on the right side of the bench.

Continuity mistake: Before Superman enters Luthor's lair, Teschmacher is laying on the couch and a bottle of Ambre Solaire is facing straight close to the TV. In the next shot the bottle is turned to the left.

Continuity mistake: After Lex Luthor opens the box with Kryptonite, Superman leans with both arms on a table. A second later he's leaning with just one arm.

Continuity mistake: The first day Clark Kent works in the Daily Planet, he sits by his desk and then a close-up shows Lois placing her hair behind her ear. In the next shot the hair has changed and is now is covering her ear.

Continuity mistake: The day young Clark Kent leaves his parents' home, there's a shot where mother is watching him from inside the house. The clouds and sky colour reflected on the glass is different to the one we see in the following angle.

Plot hole: When there is a big explosion at a plant and Superman flies in to save the day, all he does to stop the explosions is pull down the toggle of a huge switch situated on the wall; if this is all that was needed to stop the explosions, then why didn't one of the workers do it, and save Superman the trouble of flying all the way out there to do something which one of the workers could have done easily.

Continuity mistake: After Jor-El places the green crystal on Khal-El pod, it keeps changing place.

Continuity mistake: Just after Supes heard Lex with the ultrasound, he flies down to the street but at the last second he disappears.

Continuity mistake: After Superman gets soaked in Lex's pool he also gets his hair wet and messy, but when he flies up his hair is dry and combed and his clothes are dry.

Other mistake: At the time when Lois is on the train and sees Clark running alongside, she is about 8-10 years old. About 12 years later she is 30.

Continuity mistake: The blanket used by baby Kal El to get to earth is red, blue and gold. When he lands it's just red.

Deliberate mistake: At Lois' penthouse, before Superman says goodbye, the image is sharp and clear. Cuts to a close-up, and then check the next wide angle where he says goodnight and flies away: It's blurry and grainy because it's not live, but a screen with a previously shot scene to allow for the camera to turn left and, in a matter of seconds, no cuts at all, show Superman magically and quickly transformed into Clark Kent.

Sacha

Continuity mistake: When Superman lifts the plane during the storm, after the pilot asks what's going on, the copilot glances at the window grabbing its side. From the opposite angle he is away, repeating all movements.

Sacha

Revealing mistake: When Superman and Lois begin their flight from her apartment, a pair of wires suspending each of them are visible, especially on the Blu-ray.

Revealing mistake: All the footage of the missiles being launched is of a poor quality and grainy, which is inconsistent with the good quality of the rest of the shots, revealing that it's stock footage.
