NBC has ordered 20 additional episodes of a show that is off to a hot start on the network: the alternative series “The Wall.”

Executive produced by NBA superstar LeBron James and Maverick Carter and hosted by Chris Hardwick, “The Wall” is the second show to launch under the Universal Television Alternative Studio, which was announced in June. The show also comes from SpringHill Entertainment and Glassman Media.

“In its first two regular Tuesday telecasts, ‘The Wall’ has averaged a 1.7 rating in adults 18-49 and 6.9 million viewers overall, according to ‘live plus same day’ ratings from Nielsen Media Research, with both telecasts building substantially from half-hour to half-hour in virtually every key ratings category,” NBC notes in its announcement.

LeBron James comments in the announcement: “When we started ‘The Wall’ we wanted to create something that would get families excited and change people’s lives. Maverick and I couldn’t be more proud of the show’s early success and we want to keep building on that.”
