Hint for the clue that begins, “Many a night…”

When you have found the elevator room at Lamplighter Lounge, you’ll notice a number of movie quotes on the wall. The clue says, “Something is out there,” which is a reference to one of the quotes. You need to figure out “what” is out there, and one of the quotes tells you. From there, the clue’s last two lines tell you what to do with the word (for instance, ad is NOT short for “advertisement”). Ultimately, you’re trying to spell the name of a place.
