Kon-Tiki, the 1951 Thor Heyerdahl-directed documentary that inspired the Weinstein Company feature nominated for the Best Foreign Language Film Oscar this year, is getting its own day in the sun. It will air on the Sundance Channel on May 11, to be followed by the half-hour behind-the-scenes featurette Kon-Tiki: The Incredible True Story. The docu, which won the 1951 Best Documentary Feature Oscar, was comprised of footage Norwegian scientist-explorer Heyerdahl shot while sailing from Peru to Polynesia on a balsa wood raft — a voyage he completed to support his theory that Polynesia could have been originally settled by South Americans crossing the Pacific. The 4,300-mile journey took he and his crew 101 days. The feature, shot in English and Norwegian and directed by Joachim Rønning and Espen Sandberg, had its platform release last weekend in one theater each in Los Angeles and New York. It took in the specialty box office’s highest per-screen average with $11,167. Kon-Tiki: The Incredible True Story actually will premiere May 3 on National Geographic Channel during its “Night of Exploration” block. Maria Menounos hosts the docu, which features interviews about the making of the feature with Rønning, Sandberg, scribe Petter Skavlan and star Pål Hagen.
