Trivia: Near the beginning of the film, Addy's mother mentions that a movie is shooting nearby, an allusion to "The Lost Boys", which actually was partly shot at the Boardwalk in Santa Cruz.
Trivia: The voice of the Fun House Narrator is that of the film's director, Jordan Peele.
Trivia: Spoilers: Among the video-tapes seen next to the TV after the opening credits are "C.H.U.D." and "The Goonies." This is quite relevant to the plot, in which it is revealed that the doppelgangers come from beneath the ground in a series of tunnels that used to be run by the government. "C.H.U.D." is about mutant creatures that live underground and have began to rise up and attack, like the doppelgangers, and "Goonies" takes place largely in underground tunnels and caverns, much like the film's climax.
Answer: The government's intent was to create completely controllable and compliant clones to do whatever they wanted them to do. Their plan did not work out, however.
