Film rights were acquired and the game at the time was popular. Many of the props were reused, but the base walls were all new. You never wondered why there were circular viewing portals like those in a submarine in a "military base"? EDIT: This was also closer to the time Bioshock II was released, so the franchise was still fresh.
All Nite Die In (2003), begs to differ. Rights only matter when a character is directly identified in marketing or in-park print materials as the copyrighted character. Not to mention that the Body Collectors are literally The Gentlemen from Buffy.
I think you need to remove Predator from your mindset, and start thinking about a house that will make you feel a little more isolated.
Anyways, I worked in the graphics department of Universal for 5 years, up until 2009. In my first few years I was on the hands-on portion, sign making and installation, before I moved to a desk job creating graphics themselves. Graphics department is directly tied with legal, as all of their work has to be approved by legal. I'm still pretty close with a few of the guys since we all attended DAVE School together.
Again, you're completely wrong and showing your ignorance. What props, exactly, from Dead Exposure, Spawning or Clown-O-Vision were reused? HAVOC's walls and layout were almost entirely identical to those previous mazes. The reason those "submarine windows" are there is because they were there in Spawning, where you were in, you know, a sewer... they were also in Dead Exposure. That layout/house design also in no place resembles the Rapture of Bioshock. There aren't submarine windows down there, unless you're in the tiny Bathosphere (which wouldn't be included in the house for obvious reasons) - there are giant viewing windows.
Doesn't matter when the film rights were acquired. No official Bioshock tie-in house was ever planned. Believe me, if it had anything to do with the film rights, it never would've even been considered until the film was nearing release. Oh, and by the way, you got your facts on the film wrong, too - the issues were budgetary, but only because Universal wasn't willing to invest 100 million+ to make an R-rated blockbuster. They were willing to do so for a PG-13 film, but Ken Levine declined since it wouldn't be true to the property. (That story can be attributed to Levine himself in articles all over the net. No idea where your version came from.)
All Night Die-In would never be something they'd attempt nowadays with legal breathing down their throats. Hell, the sequel in 2006 faced a lot of problems since license holders (fairly) raised legal concern over Samara's appearance in The Ring sequence. Rights *do* matter - right by parody and plausible deniability are only going to get you so far. Universal has some sort of agreement with Joss Whedon, since Buffy and its characters (including the Gentlemen) have appeared officially in Universal Hollywood prior to their first appearances in Florida. The Gentlemen, by the way, have been used in official marketing materials (2005 and 2008).
Nope. It's Alien vs. Predator. Alien Isolation isn't happening (though that's cute that you tried to be cryptic about it... you're no Teebin and you shouldn't try to be).
Now see, this all makes sense. Clearly some bus-driver like rumors got passed around the DAVE school and that's where you're getting all this. That said, let's not pollute the actual narrative, shall we?
