Discovery Channel had a huge hit with Nik Wallenda's successful walk across the Grand Canyon last weekend.
The channel will go back for more with "Skywire: Nik Talks the Walk," a special at 8 p.m. Sunday.
The Sarasota aerialist will watch the Grand Canyon footage from beginning to end and describe what he was feeling during the dangerous stunt, Discovery said. He pulled off the feat without a net or a tether.
The most-watched programs in cable last week were Wallenda's walk with 10.7 million viewers and the Wallenda pre-show with 6.2 million. The show was a huge hit in Central Florida with 260,800 viewers. Only Games 7 and 6 of the NBA Finals had more viewers in this TV market last week.
