Olav Heyerdahl and Petter Skavlan discuss the film “Kon-Tiki,” based on the 1951 Academy Award-winning documentary of the same name. It tells the story of Thor Heyerdahl, a Norwegian explorer who crossed the Pacific Ocean in a balsa wood raft in 1947, with five men, to prove that South Americans could have crossed the sea and settled on Polynesian islands in pre-Columbian times. They embarked on this 101 day-long journey across 4,300 miles, while reporting back via morse code, and the whole world was following. Olav Heyerdahl is Thor Heyerdahl’s grandson and Petter Skavlan is the screenwriter who wrote the script with Thor Heyerdahl. “Kon-Tiki” opens April 26 at the Paris Theatre and the Landmark Sunshine Cinema.
