What is currently present in the twister building is completely moot and inconsequential. The entire building is going to be gutted to its hollow and massive shell and then rebuilt with two theaters and a partially glamorous (and probably art deco) retrospective queue.
Reminder to some of the newer members here that what I typed above is not a rumor, but a fact.
For me, the remaining mystery is what will be projected onto the two gargantuan screens.
