The elevator doors slide open with a hydraulic hum.

Entering the subterranean Batcave home theater, the first noticeable detail is the backlit, highly detailed, life-size Batsuit standing at attention across the room.

With a total of six Batsuits placed throughout the cavernous lair, the custom home theater almost resembles a secret underground, medieval armoury.

On the left of the custom home theater is an enormous 180in film screen with Batsuits on each side.

Art Deco-inspired architecture and an assortment of gothic pieces such as large, winged gargoyles tie-in the Gotham City theme.

Walking towards the screen are bookcases that look similar to the study bookshelves upstairs.
