Visible crew/equipment: When Eric disappears for the first time the camera spins around on Albrecht. In this shot, the shadow of the camera can be seen at his feet. (00:31:50)
Visible crew/equipment: When Lee shoots Fun Boy, Fun Boy falls backwards on to the bed. His leg flies up, and you can clearly see the cord coming from his pants that is attached to the fake blood bag. (00:39:05)
Answer: Top Dollar (the main villain played by Michael Wincott) sent them over there to talk them. He sorta explained at the end. He 'believed' that he owned the building. I think he said something along the lines of: "Hell, nothing in this area happens without my say so." I guess Eric and Shelly's complaints were going to attract attention with the authorities and Top Dollar did not want that.
