Other mistake: The crow leads Eric along a rooftop at the start in the pouring rain and down into a building. However, as Eric is walking into the building there are no wet marks from his soaking wet boots. (00:10:00)
Other mistake: When the girl is kidnapped and Eric goes to save her, he enters a big door of that Gothic cathedral (as depicted on the movie cover). At that moment, the wind blows. But for the scene to make any sense, the wind should blow from the outside in, not from the inside of the church out, but the motion of Eric's hair shows the wind blowing the wrong way. (01:05:55)
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.
