The whole elevator scene itself is a reference to The Cube in that they are in one box that moves around amongst thousands of others.
Also, where they are looking at the props in the basement a wedding dress is seen which looks like Gina Davis' dress from Beetlejuice. Moments later, Chris Hemsworth blows a horn which looks like Alec Baldwins' transformed state in the same film.
The scene in which it shows the other failures from around the world displays a castle on fire in Madrid. Did anyone feel this was a nod to Resident Evil 4 where you infiltrate the castle and you have to take out the catapults?
Also, a fat and old version of Kratos from god of war can be seen briefly after Dollfaces get off the elevator and just before the scientist gets chucked to the snake to eat.
