Corrected entry: When the RRTS squad first enters the research part of the facility they take an air sample. The sample shows Chromium, Magnesium and Lead. The symbol used for lead in the movie is Ld, not Pb as it should be.
Corrected entry: The skeleton of Lucy and her child- they wouldn't die in that position (her shielding the baby) if there were mutants/demons attacking; she'd be torn apart, thrown against a rock/wall, etc. as would the child. The only way they could die and be preserved in that manner would be if she died from a volcano (ie Pompeii). When asked "How did [she] die?" Samantha replies "We don't know". Death by volcano is easy for a master archaeologist to spot.James King III
Corrected entry: In the scene where Samantha Grimm and Duke are carrying the wounded Dr. Carmack to the lab, all of the sudden a new character appears in the scene to assist them. This brunette female in a lab coat wasn't with the soldiers or Samantha when they entered the complex through the airlock, nor was she helping them with Dr. Carmack prior to this scene. Now all of the sudden she appears from nowhere to help them and no one question who she is or where she came from. Then a few minutes later Samantha tells her to go ahead and leave to be with her daughter. What daughter? Then she just leaves the lab unescorted.
Corrected entry: In the scene where Duke and Samantha are in the lab and Goat stands up behind the glass, right before he kills himself he makes the sign of the cross. However, he touches his forehead, chest, right shoulder, and then left shoulder. The correct order is touching the left shoulder and then the right shoulder.
Corrected entry: Towards the end of the movie, the Rock and the gang get back to the arc station in Nevada and everyone in the staff gets infected. At one point, the Rock starts shooting at a monster and runs out of bullets. He throws his gun down and begins to pull his other gun off his shoulder. While doing this, he bangs the gun on a pipe behind him making a loud noise and a funny facial expression.
Corrected entry: Dr. Carmack is placed in the medical lab after being found, carried in through the nanowall. Said wall isn't left open and unwatched afterwards, yet he manages to get on the other side of it. It is established that there are other routes out of the laboratory, but if they enable one to reach the other side of the nanowall, what is its purpose there in the first place?
Corrected entry: Early in the movie, Sam states that C-24 enables greatly accelerated cellular growth and regrowth. Judging by the rapidity of mutation of the bad guys affected with it, the same applies to the 'demons'. Even more so, Reaper's wounds from before his transformation heal after it is done. However, that is not the case with Dr. Willkins' appendix, Dr. Carmack's ear, and Pinky's lower half, thus letting the viewers and characters recognize them.
