A key film in the career of director Michael Powell, The Edge of the World was his first original idea to be realized onscreen, and its success attracted the attention of producer Alexander Korda. Korda's bankrolling of Powell's next several films catapulted the filmmaker into the first rank of British directors. Powell was attracted to the idea of building a dramatic story around the evacuation of St. Kilda, an island north of Scotland, whose aging population could not sustain life there. Forbidden from filming on St. Kilda, Powell and his crew journeyed farther north to Foula, an island whose sheer cliffs play an important role in the story. Two young men, Robbie Manson (Eric Berry) and James Gray (Niall MacGinnis), disagree on their island's economic future. James loves Robbie's twin sister Ruth (Belle Chrystal). The rivalry between the two men and their strong-willed fathers threatens to tear apart the island community, but an unexpected pregnancy and a rescue in dangerous seas serve to unite the islanders in common purpose. Powell took full advantage of the magnificent locations to tell this simple but affecting story of survival and adaptation to changing times. A restored version of the film, available on video, also includes the documentary Return to the Edge of the World.
