NEW YORK — Two recent college graduates are traveling to Nagasaki to interview atomic-bomb survivors and their relatives for a documentary they will produce about peace activism.

"We hope to, with the documentary, humanize the story and have interviews with the survivors — the hibakusha, as well as their children and grandchildren, and focus on peace activism as a result of the bombing," Alex Sklyar said in New York before leaving for their six-week trip that started July 1.

As the 65th anniversary of the atomic bombings approaches, Sklyar and his partner, Carolina van der Mensbrugghe, are concerned that voices of the hibakusha are increasingly being lost as greater numbers of them die off.
