The Long Ships is a 1964 Anglo–Yugoslav adventure film shot in Technirama directed by Jack Cardiff and starring Richard Widmark, Sidney Poitier, Russ Tamblyn and Rosanna Schiaffino.

When a shipwrecked Norseman, Rolfe, repeats the story of the bell in the marketplace, and hints that he knows its location, he is seized by Mansuh's men and brought in for questioning.

After swimming back to return home, Rolfe reveals to his father Krok and his brother Orm that he did indeed hear the bell pealing on the night his ship was wrecked in Africa.

However, Rolfe's father has been made destitute after spending a fortune building a funeral ship for the Danish king, Harald Bluetooth, who then refuses to reimburse him by citing an outstanding debt.

After they sail to the Pillars of Hercules, Rolfe and Mansuh find only a domed chapel with a small bronze bell where the Viking was certain he had heard the Mother of Voices.

Frustrated, Rolfe throws the hanging bell against a wall, and the resounding cacophony reveals that the chapel dome itself is the disguised Mother of Voices.

After a costly misadventure topples the Mother of Voices from its clifftop down to the sea, the expedition finally returns to the Moorish city, Aly Mansuh triumphantly riding through the streets with the bell in tow.

However, King Harald and his men, including Krok, out to rescue the princess, have since conquered the city, and upon Aly Mansuh's arrival they leap out of hiding.

The film was very loosely based on the two volume Swedish novel The Long Ships (1941 and 1945) by Frans G. Bengtsson,[4] retaining little more than the title (of the English translation) and the Moorish settings of Orm's first voyage.
