@[estacado] Being made in the early 1920s, the film initially had no soundtrack. In 1975, the youngest daughter of the filmmakers, Monica Flaherty, returned to Samoa along with Richard Leacock and Sarah Hudson thanks to a grant from the National Endowment for the Arts, in order to record location sound and folk songs to create a synchronized soundtrack to the film, with dialogue recorded in Hawaii based on what was put together by Samoan lip readers. The sound version premiered in July 1978 under the title "Moana with Sound" and became widely available after its 2K restoration in 2014.

Is the sound recorded by the filmmaker, or is it added artificially later?

far out thanx
