Inside Warner Bros.’ secret movie props archive: Batman, Bane, the Tumbler, and more (video)

“The Warner Bros. movie prop archive is top-secret. Located at an undisclosed location somewhere outside London, the unlabelled, nondescript warehouse is home to invaluable treasures from the studio’s hit movies. It’s under 24-hour surveillance and cameras have never been allowed in — until now,” CNN reports.

CNN’s Max Foster – the first reporter ever allowed into the archive – was shown unique props from Christopher Nolan’s Dark Knight Trilogy, Harry Potter, and more. Check out his top-secret visit in the video above!
