Corrected entry: After Richter and Helm attack the Last Resort, during which Helm is killed by Thumbelina, Quaid and Melina escape into the mines with Benny to meet Kuato. After Lori and Dr. Edgemar reveal their deception, it doesn't make sense that Quaid would trust Benny, since he showed up the minute Quaid and Melina were trying to escape from Richter and Helm. This was a sign that Benny was working for Cohaagen.
Corrected entry: The atmosphere of Mars is so cold that anyone who went outside without a spacesuit would freeze instantly.
Corrected entry: After Quaid and Melina escape from Cohaagen's scientists they retreat to the Pyramid Mines in order to locate the reactor. They come upon a dead end only to find Benny lying in wait inside a tunneling machine in order to kill them. Benny had no way of knowing they would be over there - Cohaagen and Richter didn't even know they had escaped the scientists yet - so there was no logical reason for Benny to have been waiting there for them.

Corrected entry: Listen to the technician at the recall center when Arnie first gets put in the chain to begin his "vacation", right before he is introduced to his choices for women. You will hear the male lab guy say, "This is a new one, blue skies over Mars", exactly what happens at the end of the movie! So, is it all just a dream?
Corrected entry: The alien machine apparently simply heats the glacier ice to produce oxygen. However, heating ice merely creates water vapour (steam). To produce oxygen from water requires a more complicated process involving electrolysis, and could not be done in mere seconds to produce enough oxygen to cover an entire planet. If that much oxygen (and hydrogen, don't forget) was pumped out that quickly, it would produce massive storms and lethal high winds which, when combined with all the dust on Mars would sandblast everyone to death, and the resultant storms and high winds would last for decades.
Corrected entry: When Arnold's wife grabs a knife out of the sink and takes the first swing at him, you can see that there's nothing in her hand.
Corrected entry: The psychiatrist that Arnold meets in his room did in fact work closely with Mr. Cohaagen. In Arnold's memory, we see Mr. C., Richter, and some other guys walking through the room Arnold will use his 3-D holo-image in. With them is the "psychiatrist" but with some glasses on.
Corrected entry: When Arnold is in the hotel being talked down by the psychiatrist, the villains are waiting to get an elevator. When they get to the floor with Arnold's room they arrive on a different bank of elevators. They come up the main elevators only to arrive on the service elevators.
Corrected entry: The film establishes that the core of Mars is made of ice. When planets are coalescing from gas clouds, cumulative gravity draws the heavier materials into the center of the planet. This is why Earth has a nickel-iron core and even gas giants have some solid material in the center. Ice is much too light to occupy this niche in Mars and would have been crushed and replaced by heavier metals in the shell around it, even if the ice was inserted after planetary formation by aliens.Phoenix
Corrected entry: When Arnie first activates the hologram in the old factory hall and faces it, it can be seen that the holo image holds the left hand (with the hologram projector) up; the real Arnie lets his left arm dangle.
Corrected entry: Near the end of the film, where Quaid is about to get shot by the man with the bomb, (Cohagen), Melina arrives just in time to shoot him 5 or 6 times in the shoulder, then 6 or 7 more times in the chest. You can see that he is barely strong enough to pick up the remote detonation device. But, somehow, he is strong enough to keep himself from being sucked into the wind tunnel.
Corrected entry: When Cohagen is boasting about how his plan to kill Cuato was a success, he mentions that Richter wasn't aware of the plan. But this makes no sense, because if Richter had managed to kill Quaid (and he had plenty of chances to do so) then the whole plan would have failed. Cohagen would have definitely made sure that Richter had orders not to kill him.Daz
Corrected entry: In the scene after Arnold kills the construction hoods he goes home to Sharon Stone and tries to convince her that it was real by showing her his bloody hands with which he was grabbing her shoulders, yet there is no blood on her or the appliances he turned off upon entering the apartment.
Corrected entry: Never mind the absolute ridiculousness of having machine guns in a vacuum environment with many glass windows (and huge glass domes), why for safety's sake didn't the Mars colony have bullet proof glass?
Corrected entry: In the scene where Lori is fighting with Douglas Quaid, it shows her wearing a pair of brand new 1990 Ladies Nike Air sneakers, even though the film is supposed to be set quite some time in the future. It is unquestionable that Nike would have updated its product or changed to accommodate a change in fashion.
Corrected entry: In the scene where Arnold is at the front desk of the hotel and retrieves the paper from the safety deposit box, he asks for a pen. The clerk gives him a red pen to write on the back of the paper stated "for a good time, ask for Melina". When the scene cuts to Arnold writing on the paper, the ink is black. When he returns the pen to the clerk, it is red again.
