In Extraction, move fast enough to get the keycard from the guard on one of the upper floors. Head back down to the first floor and you can open the two locked doors on this floor, one being the front glass door! Careful though... walk out too far and you fall to your death! The other door has a completely motionless Mr. Blonde and A pair of dataDyne female guards. They're probably there for easy cinema access.
