More recently, the shed was converted into a studio by Hollywood giant Warner Brothers, which leased it for the filming of Batman Begins in 2004.
The Gotham City set was built inside, brought to life by dozens of local people who landed parts as extras.
The Times & Citizen understands Warner Brothers has renewed its lease on the shed for a further 12 months, and could now be in residence until December next year.
Intriguingly, signs of activity at the shed in recent days, and glimpses of cables and a lighting gantry through the massive opened doors, have prompted speculation the hangar is being freshly rigged for another film shoot.
Reports suggest filming is due to begin early next year, with Christian Bale once more squeezing into the rubber suit as Batman, and heartthrob Heath Ledger set to grin and bear it as The Joker.
