Reese Witherspoon competes with Neil Patrick Harris in daredevil stunt (Video)

Reese Witherspoon competed in a terrifying stunt with Best Time Ever host Neil Patrick Harris on Tuesday by racing up 15 stories before zip-lining back down.

ET noted that both Witherspoon, 39, and Harris, 42, looked uneasy as a crane carried them up several stories.

"That was insane, that was way higher than I thought it would be," the host commented.

Witherspoon, who admitted she was a little scared of heights, wasn’t too happy with what seemed like an endless ride through the air either.

On the way up she told Harris, "Neil, I am going to bury you.”

She also joked that he wasn’t getting a Christmas gift from her this year.

During their race on the sky-high structure they remained neck and neck for a good portion of the time. In the end though Harris beat Witherspoon by zip-lining to the ground first.

The new NBC variety show will feature the Tony Award-winning actor performing a number of stunts, pranks and skits. It is based off the British television hit Ant & Dec's Saturday Night Takeaway.

The show airs Tuesday nights on NBC.
