National Geographic Channel will air a documentary about the making of Kon-Tiki (pictured), a 2012 Norwegian feature film about explorer Thor Heyerdahl’s 1947 voyage across the Pacific Ocean on a rickety wooden raft.

Produced by the Weinstein Company, Kon-Tiki: The Incredible True Story (one x 30-minutes) will air during the channel’s weekly ‘Night of Exploration’ strand on May 3 at 7 p.m. EST/PST to coincide with the film’s theatrical run in New York and Los Angeles.

Directed by Joachim Rønning and Espen Sandberg, Kon-Tiki was shot in open waters in six countries and chronicles Heyerdahl’s trip from Peru to Polynesia in a bid to prove it was possible for South Americans to settle in Polynesia during pre-Columbian times.

The doc will feature behind-the-scenes footage and interviews with the film’s cast and screenwriters, among others.
