Movie 'The Sapphires' called Australia's version of 'Dreamgirls' – stars sit down with John Berman

The movie "The Sapphires" is being called the Australian's version of "Dreamgirls."

It's the story of four young Aboriginal women in the 1960s who form an all-girl soul group who are then sent to Vietnam to entertain U.S. troops.

The movie opens Friday for U.S. audiences in New York and Los Angeles.

CNN's John Berman had the chance to sit down with the stars of "The Sapphires" - Jessica Mauboy, Miranda Tapsell, Deborah Mailman and Shari Sebbens - to talk about the true story behind this remarkable movie, and the global response to the film.
