Watch: Bear Grylls Rappels Down Flame-Covered Building to Launch Show

To launch his new Discovery Channel show Bear Grylls: Escape From Hell, the host rappelled 150 feet down the front of Battersea Power Station amid projections of a burned-out building on the building's façade. The 3-D projection mapping showed bursts of flames covering the building as pyrotechnics flanking the action shot off. A reception and screening for 575 guests at the station followed the stunt.
