Continuity mistake: Clark is thanking Bruce for the house. They both look in the distance at Lois and Martha; there are a couple guys fetching boxes near the carpenter, on both sides of the workbench, but they are nowhere to be seen in the new closer angle. (01:45:55)
Suggested correction: Passage of time. Movies don't always show every second in real time. Martha and Lois were approaching the steps, when the boxes were being fetched. In the close-up Lois is several steps up and Martha is just stepping on them as the guys with the boxes follow. It's also depth perception. The boxes aren't near the carpenter. You can see when Clark walks up. The boxes are actually several feet in front and to the right of the carpenter. It's also very possible in the close-up, they aren't in there.
I understand the caveat about the continuity in editing since they have moved away on what would amount to a couple seconds (Lois is merely on the second step), which is a hiccup some would label error in continuity already. The boxes are not right by the workbench, but still they are near as I said; let's say the person on the left who grabbed one moved to a portion of screen where he wouldn't be visible (you do see his gloved hands); the guy in red and blue should be in frame no matter what.
Continuity mistake: When Superman is explosively resurrected by the MotherBox, it disintegrates the clothes and shoes in which he was buried, but he's still wearing pants immediately afterwards.
Suggested correction: It disintegrates most of his clothes. What he's left with are the pants he was buried in.
So, the gigantic blast vaporized his shirt, tie, jacket, shoes and even socks, but didn't affect his pants at all? Seems unlikely.
Well although I agree you gotta know that the obvious reason for this is that they didn't want them fighting a naked Superman. He is still wearing the same pants as he was buried in though, not suddenly wearing different pants. On the other hand it would have been more logical for Superman to be naked for a second or so, then in the next scene wearing something which he got from anywhere in the city in a split second. Unfortunately for the movie makers they show him wearing them as he shoots up from the building, and it's the same pants so the plausibility gets quite lost. It's not a continuity mistake though.
Whether it's plausible or not is debatable, but the original mistake claimed his pants changed. The correction is that they're the same pants he was buried in.
Suggested correction: It's never verified that his clothes and shoes were "disintegrated." He could have removed them because they were likely tattered from blasting through the roof.
True, but it's semantics? Vaporized, tattered, sliced into cubes or deep fried, the crux is still that his magic pants are intact and the rest isn't. I mean, it's pretty obvious like lionhead said in his comment, why it happened; modesty reasons. Some (not me!) might consider pedantic or too obvious to point out such an event that falls generally under the suspension of disbelief category, however it's a fact.
Continuity mistake: When Dr. Silas Stone is speaking with Victor, he is wearing a completely different set of clothes from what he was wearing at the lab in the scene just prior. It is implied that the scene happened immediately when coming home from the lab.
Suggested correction: He changed his lab coat for a regular jacket. That's not completely unreasonable going from work to home.
