There is an actual Batcave in Los Angeles, where all the old Batmen live. I can’t tell you where: I signed an NDA. But in the most unlikely neighbourhood, in the most obscure location, lies a giant warehouse where Warner Bros keeps a century’s worth of treasures, including the best vehicles from its Batman films going back to 1989.
On a tour of this warehouse, which Warner Bros calls, with a slightly villainous air, the “Corporate Archive”, I saw nine Batmobiles, in a row, gleaming. Each one is a functioning vehicle with an engine, not just an elaborate prop. The most expensive cost close to $1m. It has wing-shaped treads on the tires, so it leaves little bats in its wake.
