A special effects technician was killed while filming a sequence for The Dark Knight when a vehicle he was driving crashed during a stunt test run, according to the BBC.
The accident occurred off-set while cameras were off, according to Warner Bros. Pictures.
The as-yet unnamed stunt man was on the camera truck following a stunt vehicle on a test track at Longcross, near Chertsey in Surrey. The stunt vehicle was reportedly the Batmobile.
"A technician on the film died when the truck he was in struck a tree following a test run,” the studio said.
