Will Smith took less than 3 minutes to go from the rim of the Grand Canyon to hovering 1,000 feet over it and then plummeting out of a helicopter, but it took TONS of man hours to pull off that adrenaline rush.
T-Minus Productions, the company hired to pull off Big Willy's 50th birthday bungee jump, says they started by hiring an elite stunt performance team ... along with 2 stunt helicopter pilots and riggers. They're the guys who double, triple and quadruple checked Will's bungee cord and harness on the chopper.
The test runs started weeks ago with a stand-in who matched Will's height and weight.
