Revealing mistake: Doug has the hologram when inside the alien nuclear reactor, and a bunch of bad guys encircle the holographic image and fire at it at point blank with automatic weapons, and not one bad guy gets hit. If they encircled the 3D image, at least a few bad guys would have been hit by their own men. (01:37:00)
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: 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).
