Ra

Ra is a 1972 Swedish-Norwegian documentary film directed by Lennart Ehrenborg and Thor Heyerdahl, documenting the Ra expeditions organised by Heyerdahl in 1969 and 1970, in which he and an international crew attempted to cross the Atlantic Ocean from Morocco to the Caribbean aboard papyrus reed boats. The film chronicles both the failed first voyage on Ra and the successful crossing on Ra II, which arrived in Barbados after 57 days at sea. Narrated by Roscoe Lee Browne, the film was produced by Ehrenborg for the Swedish Broadcasting Corporation and was nominated for the Academy Award for Best Documentary Feature at the 44th Academy Awards.
