Corrected entry: The wolf and crocodile have added physical traits such as spikes and quills, but George looks exactly as he did before, with the exception of the growth.
Corrected entry: Near the beginning, they say part of the space station crashes into southern Wyoming. They then show a title card that says "Casper, Wyoming." Casper is in central Wyoming.
Correction: Parts of the space station crashed in several places. Later on, the wolf is discovered in Casper. A wolf that size and speed could easily travel a large distance in a short period of time.
Corrected entry: After the chopper crashes, Davis' shirt is very clean in spite of the dust. (01:22:50)
Correction: His shirt is not clean at all. It's got dirt, blood and rips all over it. Also a lot of that is ash, and the reason more of it is not on them is they were inside the chopper during the brunt of the fallout. So most of the bulk had settled by then. It's not unreasonable that his shirt would stay visibly white after that.
Correction: How is this a mistake? George simply didn't experience the same random mutations as the other animals. Either that, or the genes of the other species were manipulated in a very specific way on purpose.
