Question: At the beginning of the movie, Quaid has a friend at work (if my mind's not failing me his name is Harry) that tells him not to go to Recall because some person got lobotomised. Later, when Quaid is returning from Recall his friend stops him and tries to kidnap (or kill) him because Quaid "talked about Mars". I can't understand the role that this man has in the plot. Quaid told his wife that this man is a spy (I wonder how he knew that), and I'd like to know which side he seems to be fighting for (the Agency or the rebels).
Question: There is a scene in the movie in which Arnie disguises as a woman to pass the entrance control in Mars. Moments later, the mask he's using starts to malfunction and he has to take it off. When he's doing that, we can see that the man who's playing Quaid is not Arnie but a stunt double. Why did the director choose a stunt double to replace Arnie in a scene that's not risky at all?
Question: How was Hauser and Cohagen's plan supposed to work if Quad never went to Recall? Why are Cohagen's workers trying to stop him from going to Recall? His wife is constantly trying to talk him out of going to Mars and Recall, so how would Quad ever lead Cohagen to the mutant physic if he'd not gone?
Question: Why is there air in and around the reactor? Humans have extensively researched the reactor, so they obviously needed air to do it, but doesn't Cohaagen control all the air on Mars, and the reactor? So if he doesn't want anyone to turn the reactor on why not simply drain the air from the reactor so nobody could go there?
Question: In the office scene, there is a painting in the background of a rocket ship. What is this painting?
Question: Dr. Lull says that she will do as Mr. Mclane says and "cover up any memory (Quaid) has of us or Rekall." However, when Dr. Edgemar comes in Quaid's hotel room on Mars, Edgemar reminds him that his experiences on Mars have been exactly what Quaid requested in his secret agent fantasy at Rekall, to which Quaid agrees. So obviously his memory of Rekall wasn't "covered up"?
