'Amazing Race' Finale Enlists David Copperfield For Death-Defying Challenge

David Copperfield designs a death-defying challenge in Sunday's The Amazing Race All-Stars Finale and Brooke Anderson is with the master illusionist himself for a special sneak peek of the big stunt.

Sunday's finale of The Amazing Race All-Stars promises to be a show stopper with the help of illusionist David Copperfield. The final three teams are faced with a death-defying task designed by Copperfield himself.

From riding a raft over Niagra Falls to escaping from an exploding building, the master illusionist and escape artist has had his fair share of high risk stunts. But as he explains to ET's Brooke Anderson, Copperfield had much less time than usual to pull it off.

"The difference here is, with my special we had two years creating these things. We had two months to do this," he says.

In order to win the million dollars on Sunday, the final teams must escape out of a Las Vegas roadblock suspended in the air. Little do they know, the box is being lit on fire!

"Things didn't go exactly as planned so it should be interesting to watch," Cooperfield teases.

Be sure to watch the video for a sneak peek of the big stunt. To find out who masters the illusion and crosses the finish line tune into The Amazing Race All-Stars Sunday at 8/7c on CBS.
