Complete Monster: In the DC Comics adaptation of this classic action flick, by Elliot S. Maggin & Tom Lyle, Chief Administrator Vilos Cohaagen lacks his film counterpart's Villainous Friendship with Carl Hauser, while still retaining all the evil. As leader of the Mars colonization efforts, Cohaagen brutally overprices the sell of oxygen to the citizens of the colonies, uncaring that many of them are slowly dying from being unable to pay Cohaagen's prices, and, upon discovering a likely way to provide infinite oxygen across the planet, Cohaagen covers it up to retain his power over the inhabitants. When rebel forces continuously try to oust his treachery, Cohaagen devises a plan with his partner Carl Hauser to mind-wipe the latter, turning him into an ideal rebel fighter, then using this new personality, Douglas Quaid, to lead Cohaagen to the rebels. Once succeeding in this, slaughtering the entire rebel group, Cohaagen attempts to revert Quaid back to Hauser, laughing all the way about asphyxiating the entirety of Venusville for fun. Cohaagen ultimately showed his lack of care for Hauser when, after Quaid escapes the attempted reversion of his mind, Cohaagen callously orders him be killed, and spends his last moments using Melina as a hostage in an attempt to murder Quaid, securing his rule over Mars once and for all.
Crosses the Line Twice: The human shield scene. A poor bystander getting caught in the line of fire and shot by Richter's men when they're trying to kill Quaid is horrible. Quaid grabbing his corpse, using it to protect himself from several more rounds of gunfire, and then throwing his now completely bloodied up body onto his pursuers on the other hand? Hilarious.
An advertisement for Fuji Film is seen in the background of one scene. The film's creators couldn't have predicted that analog photography would be all but killed off by digital photography long before 2084 (the year in which the movie is set).
Quaid decides to have a memory implant of a vacation on Mars as a secret agent instead of as tourist, only to discover he is a secret agent. In True Lies, Arnold Schwarzenegger plays a secret agent whose wife and daughter thinks he is a computer salesman.
When Quaid realises that Lori is attempting to seduce him to buy herself some time while Richter and his goons come for him, he says "Clever girl".
