When the lead Cheap Girl tells Walter they want to change their name, you hear "Meryl Streep" but his lips say something else. The same thing for Walter when he tells him he's not changing their name. Perhaps another name was originally used and the producers didn't get the permission to use it.
Initially, the front door swings into the house and the door knob is inside and the handle is outside. They are on the left (as viewed from outside the house). After the door and frame fall off the house it is propped up in the doorway, but the door now swings outward. The door could only do that if it were propped up backward, which it is not: the door handle is still outside and the knob is inside, and they are still on the left (when facing the house from outside).
