He’s walked the walk. Now he’s going to talk the talk.

Discovery plans to re-air Nik Wallenda’s record-setting tightrope walk, only this time with audio commentary. Aerialist Wallenda will give viewers a literal step-by-step account of his crossing over the Grand Canyon at 1,500 feet last Sunday, revealing what he was thinking at each moment. The debut telecast of the walk delivered a ratings record for the network.

Discovery claims that this will be the first time Wallenda has watched the footage (really?). Skywire: Nik Talks the Walk will air Sunday night on Discovery Channel.
