[[WMG:What the sequel would have been about...]]
Everything that happened was ''real''. Quaid and Melina are living happily on Mars. However, Quaid has been having nightmares, and they're about Hauser. He wants his body back and tries to by controlling Quaid's "body". Almost like a Jekyll-and-Hyde scenario. Richter is probably still alive, and wears robotic arms. He becomes the [[DragonAscendant new Big Bad]].
* Wrong, according to Wikipedia and its more reliable sources. The sequel planned to use mutant psychics as part of a law-enforcement agency (which Quaid joins), in order to stop crimes before they actually occur. This was based on another Phillip K. Dick novel and was eventually rewritten into ''Film/MinorityReport''.
** So the sequel would be SomethingCompletelyDifferent.

[[WMG:Recall is an early implementation of Dollhouse technology]]
Before it causes all the trouble on Earth. Maybe it was Quaid's failure to go back to his original personality that made them create the call-and-response feature that keeps dolls in line.

[[WMG: The Rekall "secret agent" vacation was not a coincidence, and everything is real. It was how they planned to activate Hauser all along]]
The plan was for him to lead the BigBad to Kuato. There had to be some way of activating him after the memory wipe. Unfortuantely, things didn't quite go according to plan.
* Cohaagen specifically tells Quaid that he screwed up their plans by finding his memories too early. They weren't expecting him to go to Rekall.
** And Quaid's "best friend" was assigned to make sure he doesn't do anything to get his memories to resurface too soon.

[[WMG: Kuato is a descendant of RL Jordi Pujol i Soley, President of the Catalonian Autonomous Community between 1980 and 2003.]]
Come on, [[http://en.wikipedia.org/wiki/Jordi_Pujol look at him]]. The resemblance is uncanny.
