Ryan Gosling has joined the #KeepThePromise campaign, initiated to support the Armenian Genocide-themed drama “The Promise”.

“The war in the Congo is one of the deadliest wars since World War Two. I vow to keep the promise to help support human rights in the Congo,” Gosling said in a video message, posted on Enough Project’s twitter account.

Hollywood stars, including Cher, George & Amal Clooney, Leonardo DiCaprio, Barbra Streisand, Elton John, Sylvester Stallone, Don Cheadle and Andre Agassi have come to support the movement recently.

The film hits theaters in the U.S. on April 21.

All the proceeds from "The Promise"'s theatrical run will be given to nonprofit organizations, including the Elton John AIDS Foundation and other human rights and humanitarian groups.
