The opening scene says.....there are thousand of miles of abandoned subway tunnels, unused sewers or old mine shafts — and many have no clear purpose at all. The little girl says in the backseat "do you know the government uses fluoride to control our minds" Yea I think the movie is a mix of vrill psychology of living underground and Cloning.....the clones living underground were very jealous of their counterparts living above ground and said we didn't appreciate it as we got sunlight and real food as they cannobolized on each other and rabbit. Oh in the second scene or so the movie C.H.U.D. is on the shelf and that stands for Cannobolistic Humanoid Underground Dwellers. Yea literal White Rabbits everywhere and clones, underground tunnels and that fuckin poster and no one is gonna get the hints....maybe down the line when they find Donald Marshall they'll be like "ohhhh so that's what that movie was all about".....but yea you can't hint any louder than this and still no one is getting it
RE: So this Movie called Us, about 'dopplegangers' attacking a family is another hinty cloning movie that i care not to watch
